基于MATLAB/xPC Target的抽水蓄能机组调速实时仿真系统

利用MATLAB软件提供的Simulink,RTW,xPC Target等工具箱建立了抽水蓄能机组的实时仿真模型,并通过输入/输出接口电路将实时仿真模型与实际抽水蓄能机组调速器相连接,构成了一个半物理实时仿真系统。利用某电站抽水蓄能机组参数对该系统进行了测试验证,结果表明,该实时仿真系统建模方便、能自动生成高效仿真程序、参数调整灵活、试验曲线与原型机组试验曲线吻合度高,可作为调速器开发设计阶段的试验平台,以及试验验收阶段机组动态特性的测试系统。

Real-time Simulation System for Governor of Pumped Storage Power Unit Based on MATLAB_xPC Target

Real-time simulation model for governor of pumped storage power unit(PSPU) is established by using toolbox of MATLAB,such as Simulink,RTW and xPC Target,etc.The real-time simulation model and a governor of PSPU are connected with input-output interface circuits to constitute a semi-physical real-time simulation system.Tests are carried out for verification with the parameters of a real PSPU.Test results show that the real-time simulation system has advantages such as: conveniently modeling,automatically generating effective simulation program,flexibly adjusting parameters,and test curves greatly coincide with these of prototype test.This simulation system can be served as a test platform in the design stage of governors,and as a test system of PSPU dynamic characteristics in acceptance test stage.
