水轮机调节系统对象实时仿真研究

Study on Real-time Emulation of Speed Governing System for Hydraulic Turbine

本文描述了以微机 PC/XT 为基础的实时仿真系统的建立及仿真采样时间的选取。该系统可对起动,停机,空载扰动;单机增、减负荷,甩负荷;并列工作增、减负荷等工况进行实时仿真。利用该系统还可进行调速器静特性,转速死区和滞迟时间等的测定,并可进行现场动态试验和记录。

The methods about setting up a real-time emulation system based on a micro- computer PC/XT and selectting of samplling-time at emulating are described in this paper.This system can emulate following operating regimes:starting-up, shutting-down and no-load disturbing for a unit;and increasing/decreasing of load and rejecting of load in a insulated network;also increasing/decreasing of load in parallel operating.This system can be used for measuring of static char- acteristic,speed dead band and delay time of a governor in shop;as well for test- ing and recording of dynamic behavior on site.
