WOODWARD MSLC-2 8440-1977 Microprocessor-based Load Control Module

Synchronization Function: It can provide phase matching or slip frequency synchronization, achieve voltage matching at the grid-connection or tie circuit breaker, allow selection of slip frequency or voltage phase matching synchronization, and also has a two-side dead bus option, providing sufficient flexibility for tie and main tie applications.

Load Control: It can sense True Root Mean Square (RMS) power, realizing shock-free loading and unloading with the public power grid. It has basic load, import/export, process and utility unloading modes, which can simultaneously control the active power (kW) between different power sources, and accurately control the reactive power (VAR) and power factor.

Communication Capability: It communicates via Ethernet and supports redundant Ethernet communication to enhance reliability. It also supports the Ethernet Modbus TCP protocol, facilitating remote control and monitoring through PLC or DCS systems.

Control Capability: One MSLC-2 module can provide master control for up to 32 DSLC-2s and 15 additional MSLC-2s in the system. When used in combination with DSLC-2, it can handle multiple utility connections for up to 8 bus segments.

Input Characteristics: Equipped with 1A CT input, which can meet the requirements of three-phase electrical parameter measurement and control.

Power Supply Requirements: The operating voltage range is 8 to 40 VDC, supporting 12/24 VDC power supply, with a wide voltage adaptation range to adapt to different power supply environments.

Wiring Phase: It can be set to 3-phase 4-wire wiring phase, which can flexibly adapt to different wiring modes of power systems.

Power Stations: In various power stations, such as thermal power generation, hydropower generation, wind power generation, etc., it is used for synchronization and load control of generator sets, ensuring stable connection and power transmission between generator sets and the power grid, and improving power generation efficiency and power quality.

Industrial Automation: In the captive power plants or industrial power systems of some large industrial enterprises, the MSLC-2 module can be used to coordinate the operation of multiple generators, realize precise control of power demand in the industrial production process, and ensure the stable operation of industrial production.

Power Grid Systems: In places such as substations and switch stations of the power grid, it is used to control the power distribution and transmission between different power sources, realize the stable operation and load balancing of the power grid, and improve the reliability and flexibility of the power grid.
