WT(WST) MULTI-SYSTEM CONTROL AUTOMATIC SELECTION MICROCOMPUTER GOVERNOR
WT(WST) multi-system control automatic selection microcomputer governor adopt the proportion servo valves with high accuracy, high reliability, high dynamic characteristics for main mechanical hydraulic system.When there is no power supply voltage, A hydraulic protection function is automatic formed by Proportion servo valves to ensure the security of the system and operation.
At the same time electro-hydraulic reversing valves is used as backup and manual control system. After power off,Automatically switch to machine manual control and and keep the operation status of power cuts. Main distributing valve is cancelled.
The advanced adaptive type PID variation parameter and variable structure control method is used in the electrical control,also advanced digital frequency measurement method, the closed-loop control system with the guide vane move, friendly human- machine conversation interface. Make the hydropower turbine safely run in the various operating condition,Realize the function of the automatic and manual start, grid generation,emergency stop etc.
