风电机组变桨距系统半实物仿真试验平台

为了解决大型风力发电机组出厂前设计整机控制系统试验投入较大问题，针对大型风电机组的变桨距系统半实物仿真平台进行试验研究，并给出了在工厂内进行变桨距控制系统性能测试的解决方案.整个半实物仿真平台采用软件模拟各种工况和载荷情况，以运行控制系统（包含变桨距控制策略）和电动变桨距执行机构为实物形式，通过信息的实时交互完成了控制性能与执行机构的测试及载荷等模拟.仿真结果表明，案例研究有效验证了半实物仿真试验平台的合理性，此方法可以为机组设计和后续生产调试提供可靠的参考依据和验证手段.

Semi-object simulation test platform for variable pitch system of wind turbine

In order to solve the larger investment problem in testing the whole unit control system of large-scale wind turbine before product delivery,the semi-object simulation platform for variable pitch system of large-scale wind turbine was experimentally investigated.In addition,the solution for the performance test of variable pitch control system in the factory was proposed.For whole semi-object simulation platform,various operating conditions and load situations were simulated with the software.The operating control system containing the varible pitch control strategy and dynamoelectric variable pitch actuator were taken as object form.Moreover,the test of control performance and actuator as well as the load simulation were completed through the real-time interaction of information.The simulation results show that the case study verifies the rationality of the semi-object simulation test platform,and this method can provide the reliable references and verification means for the design and successive adjustment of wind turbine.
