Peak200

PEAK200-HVAC  8200-1501

Digital Control for Steam Turbines

The Peak200 controller is designed to

operate small single valve, or single valve

rack industrial steam turbines. This cost

effective steam turbine controller includes

specifically designed algorithms and logic

to start, stop, control, and protect small

industrial steam turbines or turbo

expanders driving compressors, pumps, or

industrial fans.

The Peak200 control’s unique PID

structure makes it ideal for applications where it is required to control steam plant

parameters like turbine speed, turbine load, turbine inlet header pressure, turbine

exhaust header pressure, pump flow, or compressor discharge, or suction pressure.

The control’s special PID-to-PID logic allows stable control during normal turbine

operation and bumpless control mode transfers during plant upsets, minimizing

process over or undershoot conditions. The Peak200 controller senses turbine

speed via passive speed probes and controls the steam turbine through an actuator

connected to the turbine inlet steam valve(s). Peak 200 includes Woodward’s

patented adaptive PID controller that allows users automatic calculation for optimum

dynamic gains at their individual plant system.

Designed to function as a plant DCS node the Peak200 controller can be configured

to interface with the plant DCS via hardwired inputs/output signals or serial or

Ethernet communications. With the capability to monitor and control all turbine and

driven equipment based functions (i.e. bearing temperatures, vibration levels, control

oil levels, etc.) the Peak200 controller is ideal for use as a cost-effective turbine

control/protection as well as plant DCS monitoring node.

Alternatively the Peak200 can be configured to accept a remote turbine speed/load

demand from the plant DCS via a 4-20mA signal, discrete raise/lower commands, or

Ethernet or Serial Modbus communications.

PEAK200-HVAC 8200-1501

The Peak200 control also includes a special “Cascade” PID control function that can

be optionally configured and used to control any system process, related to or

affected by turbine speed or load. Typically, this controller is configured and used to

control turbine inlet header pressure, turbine exhaust header pressure, pump flow, or

compressor discharge, or suction pressure. The Cascade PID compares a 4–20 mA

process signal with an internal set point to directly position the Speed PID

controller’s setpoint, thus changing turbine speed or load until the process signal and

set point match. By cascading these two PIDs in this fashion, bumpless transfers

can be performed as well as turbine min/max.

Ethernet and serial communications allow users to easily connect the Peak200 in to

plant or process control system. All controller inputs, outputs, and statuses can be

monitored and all start/stop or enable/disable commands can be given through

industry standard Modbus TCP. The Peak200 uses SNTP (synchronized network

time protocol) over Ethernet to allow users to synchronize the Peak200’s real-time

clock to the plant distributed control system.

PEAK200-HVAC 8200-1501

The Peak200 control is available in either bulkhead models designed to be mounted on a wall or skid near the

turbine or panel-mount models designed to be installed within a standard panel or cabinet door. The product is

designed to meet NEMA 4x corrosion resistance tests and has an ingress protection rating of IP56. protecting it

against dust and water jets.

The control’s front panel serves as both a programming station and operator control panel (OCP). This user-friendly

front panel allows engineers to access and program the unit to the specific plant’s requirements, and plant operators

to easily start/stop the turbine and enable/disable any control mode.

Password security is used to protect all unit program mode settings. The controller’s 5” graphical display allows

operators to view actual and setpoint values from the same screen, simplifying turbine operation.

Turbine interface input and output wiring access is located on the controller’s lower back panel. Un-pluggable

terminal blocks allow for easy system installation, troubleshooting, and replacement. Optionally users can increase

the number of inputs and outputs signals to/from the Peak200 control by connecting LinkNet-HT distributed I/O

nodes to the controller’s CAN communication ports and configuring the Peak200 control to use the connected

distribute inputs and outputs. The following additional I/O signals can be connected to the Peak200 control via CAN

communications:

• (8) 4-20mA input channels and 2 4-20mA output channels (via 1 LinkNet-HT AIO module)

• (8) RTD signals (via 1 LinkNet-HT RTD module)

• (16) Discrete Inputs (via 1 LinkNet-HT DI module)

• (16) Relay output drivers (via 1 LinkNet-HT DO module)

Designed for steam turbine control, the Peak200 control includes two PID controllers (Speed & Cascade) multiple

startup routines (manual, automatic, remote control), and multiple protection functions (overspeed, critical speed

range, etc.) which can be configured by a user depending on the specific turbine application’s requirements. Users

can configure the Peak200’s different PID controllers, start routines, and protection levels themselves without the

need for a special control engineer. Once configured, the Peak200 performs a configuration check routine to ensure

that the programmer did not make any basic configuration mistakes.

Optionally users can utilize Woodward’s RemoteView software program with the Peak200 to function as a remote

operator control panel and or engineering station. This software program once loaded onto a remote computer or

touch panel, allows the user the following additional functionality:

• Perform the identical Peak200 front panel display functions (monitor, operate, tune, and configure) on the

respective computer or touch panel.

• Full function free for 2 hours

• Licensable for continuous GUI operation

• Password based login level security is utilized allowing function management for RemoteView applications

Refer to Woodward product specification B03424 for additional information.

The Peak200 includes a suite of service tools to allow users to perform the following functions:

• Upload configuration settings files from the Peak200 to save on another device

• Download configuration settings files to the Peak200

• View real-time or saved trend files

Cost-Effective Design— The Peak200 control is

designed to function as the turbine control, system

sequencer, operator control panel, and first-out indicator.

This encompassing design minimizes external system

devices as well as system installation, wiring, and

troubleshooting. This field configurable controller allows

major functional changes to be made at site, often by

knowledgeable plant personnel, and minor functional

changes to be online as process changes require. The

Peak200 control’s first-out-indicator logic indicates

internal as well as external system related alarm and

shutdown conditions, greatly simplifying and reducing

system troubleshooting.

Communications— The Peak200 controls can

communicate directly with plant Distributed Control

Systems and/or operator control panels, through two

Ethernet ports using Modbus TCP or UDP

communication protocols or via a serial Modbus port.

The Peak200’s serial port supports RS-232 or RS-485

communications using ASCII or RTU Modbus protocols.

Communications between the Peak200 and a plant DCS

can also be performed through hardwired connections.

ESDR 4

Current Differential Protection Relay

The ESDR 4 is a three-phase current differential protection relay for generators and motors (protected object).

The currents flowing in the individual lines are each measured using a current transformer on both sides of the

protected object. They form the protection area boundary or zone. All two or three-phase short circuits and line

to-earth faults within this protection area are detected by the ESDR 4 as fault currents which initiate tripping.The

unit does not trip if fault currents occur outside the protection zone. In this way, a selective protection is guaran

teed.

The unit monitors six (6) measured currents via isolated inputs. The unit calculates internally the restraint current

(Is) and the differential current (Id) separately for each phase. The actual values of the calculated parameters (Dif

ferential current Id und Restraint current IS) are shown on the display either as absolute values or as a percentage

of the generator rated current (selectable in locked input mode).

ESDR 4

Theoretically the currents Ia and Ib are equal, both in fault-free operation and outside the protection zone (Figure

4-1-a).The difference is zero and the differential protection does not initiate. However, in practice current differ

entials do occur (= spurious currents), even in fault-free operation. They result, for example, from summation or

phase angle errors in the CTs, which are influenced by deviating burden values. These spurious currents remain

small inside the operating range, but increase with increasing load and are especially high when one or more CTs

become saturated (e.g. in the case of an external short circuit). In order to prevent a tripping of the relay due to

spurious currents, the trigger threshold is not held statically constant but increases in relation to the restraint cur

rent Is.  Spurious currents need to be taken into account when adjusting the trip characteristic.

When a fault occurs inside the protection area (Figure 4-1-b), unequal currents flow in the CTs, which result in a

current differential. If this exceeds the differential protection threshold, the relay will trip.

Monitoring of the Differential Current

ESDR 4

The monitoring of the differential current is carried out in two stages..

The first monitoring level serves as a warning and can be enabled or disabled. Should the adjustable warning

characteristic be exceeded, a text appears in the display and a relay contact is enabled. The pick-up time and the

dropout delay of the relay output are adjustable. The warning stage of the monitoring is auto-resetting.

The second stage of monitoring (main stage) serves to initiate tripping. In contrast to the first stage, it offers the

possibility to monitor the overstepping of an adjustable tripping characteristic (Id < In) and additionally, a fixed

tripping-threshold of 100%, relative to the generator rated current (Id > In). The trigger-delay for each limit value

may be independently adjusted, thus allowing a shorter triggering time at higher differential currents. When one

or both tripping characteristics are exceeded, a text display is initiated and two relay contacts are energized. The

tripping characteristics possess a 2% hysterisis relative to the generator rated current. .

The signal relay is only automatically reset if the function “automatic reset relay” in the Entry field on the screen

is configured to “on”. Otherwise, the resetting is carried out by pressing the “Clear” button on the front of the

unit or via the discrete input terminal 18 “reset”.

The two monitoring levels can also be used to change the characteristics of the control function (stage 1: small

value and a long time; stage 2: high value and a short time)

Tripping Characteristic

The following figure shows the tripping and warning characteristics (with sample values for X12. Y1.and Y2). It

represents the tripping and warning thresholds (Y) relative to the restraint current (X) The positions of the corner

points are determined by the coordinates P (X12/Y2) and P (X12/Y1). The selection of these positions is depend

ent on the generator being protected. The following gives the ranges of tripping and warning thresholds:

IS / IN

IS / IN

IS / IN

0 to X12

X12 to 5 × IN

> 5 × IN

The threshold Id is independent of the restraint current..

The threshold Id is dependent on the restraint current. A change of 100% in the

restraint current causes an increase of 10% in the tripping threshold.

The threshold Id stays constant at 85%.

Different characteristics can be chosen for the first and second monitoring levels, whereby the horizontal position

(X-coordinate) is valid for both stages. The vertical position (Y-coordinate) can be chosen separately for each

monitoring level. This results in a fixed difference in thresholds of the first and second monitioring levels for

each restraint current Is.

When this input is energized, the unit locks into Configuration mode and stays in this

mode until the terminal is de-energized.

If this input remains energized for at least 1 s, the faults detected in monitoring

level 2 are reset. This means that the relays will be de-energized and the text display

will be deleted from the screen as long as the monitored currents are not exceeding

the configured threshold level.

When this input is energized, the differential protection is disabled.This means that

the differential current is not monitored, no relay can be enabled and no text is dis

played.

This relay becomes enabled when the unit detects threshold limit 2 (main stage) has

been exceeded. The configured differential current characteristics and delay time will

determine how relay 1 functions.

This relay becomes enabled when the unit detects threshold limit 2 (main stage) has

been exceeded. The configured differential current characteristics and delay time will

determine how relay 2 functions.

This relay becomes enabled when the unit detects threshold limit 1 has been ex

ceeded. The configured differential current characteristics and delay time will deter

mine how relay 4 functions.

This relay is enabled when the unit is operational and the differential current is being

monitored. The relay becomes disabled if the monitoring is deactivated through any

of the following reasons:

• the internal self-monitoring has detected a malfunction of the unit. A correct func

tioning of the unit cannot be guaranteed and corrective action may be necessary.

• the set values for parameter “CT-ratio” or parameter “Generator Current” are out

side the permissible limits (see page 19).

• the digital input “Blocking” is energized.

• the parameter “Monitoring” is configured to “Off”.

When in configuration mode (simultaneous pressing of “Digit↑” and “Cursor→”), the configuration screen can

be advanced by pressing the “Select” button. Should there be no entry, parameter change or other action for 60

seconds, the unit will automatically revert into Automatic mode.

During the configuration mode, the monitoring function is still active. This means inevitably, that while adjusting

parameters during operation, it is possible to cause a tripping of the relay.
