Working state control system and method for black-start electric control system of water turbine speed regulator

Abstract

The invention relates to a working state control system and method for a black-start electric control system of a water turbine speed regulator, in particular to eight working states of the electric control system under the black-start condition of the water turbine speed regulator. The invention relates to an electric control method and an execution control method in each state, namely, a shutdown standby state, a startup process state, a no-load state, a load state, a shutdown process state, a black-start startup process state, a black-start no-load state and a black-start shutdown process state which are mutually switched in turn, and aims to solve the problem that in the black-start process of a speed regulator, in an automatic or manual mode, the speed regulator cannot be powered on or powered off. Meanwhile, the problems of smooth transition, reasonable conversion and the like of the eight working states of the electric control system of the water turbine speed regulator when the automatic mode and the manual mode are mutually switched are solved. The speed regulator electric control system can normally control and regulate the guide vane opening degree, the unit power and the unit frequency under the black-start working states of the speed regulator, and the control target of the working states is achieved.

Description

technical field [0001] The invention belongs to the technical field of control of an electric control system of a speed governor of a water turbine generator set, and in particular relates to a system and a method for controlling the working state of a black start electric control system of a water turbine speed governor.
