摘　　要：研究全新的互联电网运行控制性能评价标准构建理论,揭示出:区域控制偏差和频率偏差等物理量的时间序列中蕴含着各种频率调节手段的控制信息,可利用傅里叶分解等数学手段对其处理,得到不同波动周期的时域分量;通过对区域控制偏差和频率偏差序列各频段相应分量间的相关性分析,达到单独评价每种频率调节手段控制性能的目的,从而实现控制性能的精细与准确评价.并设计出新一代的互联电网运行控制性能评价标准.The performance evaluation criterion designment theory for new interconnected power grid operation and control is investigated in this paper.It is revealed that there are many frequency adjustment control information contained in the physical time series,such as regional control deviation and frequency deviation etc.Matematical methods such as Fourier decomposition can be used to process the information,the time-domain components in diverse fluctuation cycles are obtained.By analysing the correlation between area control error and frequency deviation at different frequencies,the control performance for each frequency-adjust method can be evaluated,then precise control and assessment can be achieved.Accordingly,a new generation performance evaluation criterion of new interconnected power grid operation and control is designed.
