Engine Generator Control Pack/Load Distribution (EGCP-3 LS)

The Woodward EGCP-3 LS controller is a microprocessor-based load controller designed to work with Woodward speed controllers and automatic voltage regulators for three-phase AC generators.

EGCP-3 LS is a synchronizer, a load controller, a dead bus closing system, a VAR/PF controller, a process controller, power and energy measurement and protection relays all integrated together.

The EGCP-3 LS is installed on a chassis in the front cabinet and has a keyboard and two 4-line display panels.

The display can be configured and set according to specific on-site requirements. The display can also be used for normal operation services to monitor operations and view alarm data.

All functions performed by the front panel and all parameters monitored can be obtained through three serial ports.

These ports can be configured to use Woodward Watch Window software, which is an external HMI and Modbus communication, or Servlink DDE software.

The 505 can be configured to use the EGCP-3 LS only as a synchronizer or as a synchronizer and load controller

. EGCP-3 LS provides phase matching or slip frequency, and is connected to the generator set’s automatic voltage regulator to match the voltage before parallel operation.

It is controlled by a speed bias signal with 505 to regulate the generator frequency and phase. position.

When configured to use only the EGCP-3 LS as the synchronizer, 505 must be configured to receive the EGCP-3 speed bias signal through the analog input, and this input can be enabled via contact input or function key.

When used as both a synchronizer and a load controller, the EGCP-3 LS performs automatic synchronization while the load is controlled according to the operation mode of the EGCP-3. The EGCP-3 LS can be set to basic load, load allocation, remote load settings, or process control mode, depending on the configuration and system conditions.

The load allocation mode of the EGCP-3 LS is used to distribute the load to any other units using the EGCP-3 LS and connected to the same isolation bus.

When paralleled to the grid, this mode is used together with the EGCP-3 MC to allow the EGCP-3 MC to control the power plant frequency or load, depending on its operating status.

The remote load setting mode of the EGCP-3 LS allows a remote 4-20 mA signal to set the load. EGCP

The process control mode of 3 LS allows control of any process directly related to the generator load.

After synchronization, the generator load can be controlled either by EGCP-3 LS (via 505 synchronous/load input) or by the internal speed/load setpoint of 505.

When the synchronous/load input is configured, the position of the grid breaker contacts is selected for the generator load control through EGCP-3 LS or the internal load setpoint of 505.

Once the generator is synchronized with the EGCP-3 LS software load, there are operation modes (base load, load distribution, process control) for the unit to the load setting.

When an instruction is received, EGCP-3 LS can also perform software de-synchronization of the unit, while issuing a breaker open command at a set power level.

The PowerSense board receives PT and CT inputs for the generator and bus for the calculation of parameters used by the system controller in EGCP-3.

The used algorithm is based on IEEE 1459-2000. The following parameters are provided for the generator and bus: Hz, Vac, Amps, W, VA, VAR, PF, phase, voltage offset, current offset, negative phase sequence voltage, negative phase sequence current.

An optional 4–20 mA analog output is available: synchronous oscilloscope, generator measurement, line measurement.

Overfrequency/Undervoltage (810. 81U)

Directional (Forward/Reverse) Power (32) *

Negative Sequence Overcurrent (46)

Apply 505 together with redundant I/H or I/P converters

505 can be applied in single or redundant actuator systems. For redundant actuator applications, the actuator

channel 1 is configured as the leader for HP instructions, and channel 2 is configured for zero-offset HP2 requirements. This

The selection of providing the full current to the driven equipment from the two actuator drive circuits can be accomplished using a diaphragm valve or a solenoid valve.

The converter state (I/H or I/P) and the pressure feedback signal can be selectively configured into 505. If necessary, the relay output can be configured to switch between the converter outputs.

The manual switching between converters can be initiated by discrete input, Modbus or PC interface commands.

The automatic switching between converters is provided by 505 based on the driver failure, converter state, converter output pressure and the servo mechanism input pressure feedback signal.
