Description

Technical Field

[0001] The invention relates to the technical field of water turbine speed regulating systems, in particular to a speed regulator operation monitoring system. Background Art

[0002] The turbine speed control system consists of a turbine control system and a controlled system. The speed governor sends the unit information to the controller through peripheral sensors such as water level, frequency, active power, and guide vane opening. The controller combines this information with the control instructions on the monitoring system or the speed governor panel to determine the current working status and control target of the unit, and sends the control signal to the actuator. After the control instruction is converted by electro-hydraulic conversion, it finally acts on the guide vane relay, thereby changing the operating status of the unit and achieving the expected control target. However, the previous speed control system has a single function and is inconvenient to operate, making it difficult for staff to effectively manage and monitor the entire system. Therefore, it is necessary to design a speed governor operation monitoring system to solve the above problems. Utility Model Content
