Research Of Hydraulic Turbine Regulator Based On Nine-point Controller

A new study is made to complete a hydraulic turbine computer-controlled system based on the fund project "nine-point controller" of Wuhan University of Technology.Hydraulic turbine regulator is one of the important systems for operating quality and security of electrical power plant .Hydraulic activator technology has been improve to more high level-both adjusting and monitoring is integrated to form a field network control system which breaks the traditional control mode and in which industrial computer control technology , especially high reliability PLC , digital-networklized field bus technology and computer monitoring are used. Its hardware construction is composed of the productrial control computer with field bus (STD bus and VME bus), programmable controller(PLC) and productrial PC computer(IPC bus and PC bus). The import activator mostly use VME bus productrial control computer PLC and IPC.In most cases, the reliability and feature is based on the control strategy of system. The traditional PID control and all sorts of intelligent control have their advantages and defects. Thinking of the hydraulic turbine governor system is a time mutative, fast unlinearity system, it is necessary to improve its feature and reliability with intelligent control system. Therefore, a hydraulic turbine regulator based on nine-point controller is made in this paper.The paper discusses the construction, adjust processing and control algorithm of the system. In addition , it analyzes the stability and the means of obtaining parameters. The paper authenticates the feasibility of the system with MATLAB simulating. The hydraulic turbine regulator with nine-point control has a great applied prosperity.
