Description:
What is the hydro power plant Governor?
Introduction of W(S)T type governor
W(S)T type consists of microcomputer governor and hydraulic servo. The hardware adopts modular construction with the characteristics of highly dependability, compact structure, convenient operation, high liability, fast response time, easy to operate, repair, and expansion, strong ability of resisting oil pollution, etc..
Apply to large type Francis turbine generator set, Axial-flow turbine generator set and Tubular turbine generator set.
The microcomputer controller adopted imported programmable logic controller as central control unit, and touch screen as the man-machine friendly contact surface. The Ethernet, RS232, RS422 or RS485 were used as communication interface. Both AC and DC power supply systems were put into the speed governor, which can transfer into manual operation when the AC or DC functionalities have gone.
The hydraulic servo system use stepper motor to control the main distributing valve directly and the whole part of machine adopt the integrated block type composite structure and is gasket mounted.
The W(S)T type microcomputer governor adopts adaptive variable structure, changing the parameters and parallel PID regulating mode, which can materialize the various operation of the Units such as automatic switch, shut down, frequency modulation, increase or decrease of the load, emergency shut-down etc, all of which can be controlled by the governor from the machine or even remote control. The net frequency adjustment can be automatically traced in no-load condition and quick grid-connection without impulse. This software has strong functions in self diagnosis, fail-safe, fault-tolerant and error correction to ensure the unit’s safe operation. Furthermore, it could configure the color touch screen, improve governor’s water level control and regulate the power according to the user’s needs.
Functions of CJWT series governor
The pulse valve use Rexroth series valves.
The electric control part use programmable logic controller (PLC) as control core, and hard ware speed counter PLC is applied to frequency measurement directly, which promised the safety and anti-interference ability of the operation from the perspective of hardware facility.
On-line diagnostics direct at frequency signal and feedback quantity, maintain the opening under following circumstances: line broken, short circuit, controller power-losing, switch of AC and DC. Unconditional and without disturbance to changing between manual and automatic operation smoothly.
Governor compatible with the plant control loop, the following functions can be realized: starting up, halt, frequency adjustment, schedule opening, add or decrease the load, closing down urgently, manual operation.
Touch screen as the man-machine friendly contact surface.
Supply both AC and DC at the same time, or switch the current at will. (Dual power supply simultaneously but DC has priority)
