广东省联合循环机组调频扰动试验研究

Test and Research on Frequency Regulation Disturbance of Combined Cycle Units in Guangdong

在分析广东省内E级双轴和F级单轴联合循环机组的控制特点和一次调频逻辑的基础上,利用扰动试验测试机组的一次调频响应来分析、比较各类型联合循环机组的一次调频特性及其对电网的影响,试验数据说明,在电网中配备一定数量的联合循环机组有利于提高电网的稳定性。最后,针对性地给出提高联合循环机组一次调频性能的改进建议。

Based on analyzing the control characteristics and the F-class single shaft combined cycle units in Guangdong, China, primary frequency regulation logic of E-class two-shaft and the primary frequency regulation features and the effect on power network of various combined cycle units are studied by disturbance test on primary frequency regulation response. The test result shows that a specific percent of combined cycle units are helpful for power grid stabilization. Methods for improving the primary frequency regulation performance of combined cycle units are presented as well.
