摘要

对某火电厂再热凝汽式汽轮机的调速系统参数进行测试

采用电力系统综合分析程序(PSASP)的用户自定义建模功能(UD)建立了机组协调控制方式下的调速系统模型

并分别在功率及协调控制方式下

对机组调速系统参数测试的结果进行了仿真校验和现场试验。结果表明:该模型能够较好地与实际工况相吻合;调速系统的控制方式对发电机组的功率响应特性具有显著影响。

Abstract

The governing system's parameters of reheat condensing turbine in a power plant were tested.By applying the user defined modeling function(UD)of power system analysis software package(PSASP)

the turbine speed governor system model in coordinated control mode was established.Moreover

according to the parameter test results

simulation verification and field test were performed under conditions with different powers and coordinated control modes.The results show that

the established model can agree well with characteristics of the actual power unit

and control model of the governing system has significant effect on the unit's power response performance.
