优化风机制系统的性能已成为风力发电领域研究的重点。通过现场试验优化控制系统,具有危险性大的缺点。通过搭建的dSPACE仿真测试平台模拟机组的运行条件和现场环境,在仿真测试平台上进行风机控制系统的设计和算法的研究和优化,可以避免现场测试带来的缺点。在基于dSPAC仿真测试平台上进行了主控系统的安全链回路可靠性测试和偏航解缆程序、机组逻辑保护程序正确性的验证,并给出了测试结果;在此基础上深入研究了变桨变流控制算法,引入发电机加速度变量进行变参数控制并与变桨控制协调配合进行了风速突变的动态测试,试验结果表明该算法可以提高机组抑制阵风的能力和动态响应能力,优化了控制系统的算法和风机控制系统的性能,增强了机组的安全性。
Optimizing the performance of wind system has become the focus of wind power research. Optimizing the control system through on-site testing has the disadvantage of great danger. The dSPACE simulation test platform is used to simulate the operating conditions of the unit and the site environment. The design and algorithm of the fan control system are researched and optimized on the simulation test platform to avoid the shortcomings brought by the field test. Based on the dSPAC simulation test platform, the reliability test of the safety chain loop, the program of yaw release, the verification of the correctness of the unit logic protection program and the test results are given. On this basis, Propeller variable flow control algorithm is introduced, the variable acceleration variable is introduced to control the variable parameters and the dynamic test of the sudden change of wind speed is carried out in coordination with the pitch control. The experimental results show that this algorithm can improve the ability of the unit to suppress the gust and the dynamic response ability, and optimize the control System algorithms and fan control system performance, enhanced unit safety.
