Abstract

PURPOSE: To increase the reliability of flow constant control by duplicating the power-flow conversion unit detecting flow from the power generated in a series hydraulic power station and using the failure diagnosis input from the guide vane opening versus flow conversion unit system as one example.
CONSTITUTION: When the objective load instruction 6 is instructed, the control signal formed with the load sharing and flow correction unit 7 is fed respectively to the governers 4A and 5A of the upper and lower stream generating stations. The flow of the stations is detected at the upper and lower stream flow detectors 8A and 8B and fed back to the unit 7 as the flow Q1 and Q2. On the other hand, the powers P11 and P12 of the stations are detected and they are converted into the flows Q11 and Q12 with the power-flow conversion units 43 and 44. The flows are compared at the duplication monitor unit 45 to form the flow Q1. If either of the units 43 and 44 is in failure, the hydrualic turbine flow Q10 based on the guide vane opening GVO1 is inputted to the failure diagnosis unit 49 together with Q11 and Q12, and the flow not present in failure is selected at the selector 50 to obtain the flow Q1.
