YWT microcomputer hydraulic speed governor adopts high-performance programmable controller as the main body of the hardware and cooperates with appropriate mechanical hydraulic follow-up system to realize speed regulation and output control of hydro-generator.

Programmable logic controller is a microprocessor-based, integrated modern computer technology automatic control technology and communication technology developed a common industrial automatic control device Small size, strong function, high reliability, simple program design , Easy maintenance, etc., especially to adapt to harsh industrial environments.

Main Specifications

1, the unit grid frequency signal: the signal voltage normal working range: 0.5-130V; normal frequency measurement range: 5-100HZ; frequency measurement accuracy: ≤ ± 0.002HZ

2, guide vane position anti-t expensive signal: the operator to provide voltage: +24 V; guide vane position anti-1l expensive voltage: guide vane opening 0-100% corresponds to 0.5-10V.

3, the switch input signal: circuit breaker position state start signal contact, stop signal contacts, guide vane opening increased contacts, vane opening to reduce the contact.

main feature

1, the use of programmable logic controller as the main hardware, high reliability, MTBF ≥ 25000 hours MTBF.

2, with frequency (speed), opening adjustment mode, to adapt to different operating conditions of hydr opower plant requirements.

3, the frequency (speed) measurement by the PLC to achieve, the external circuit simple, improve the machine"s anti-interference ability and reliability.

4, the frequency adjustment mode using PID regulation law, opening the use of PID regulation.
