摘要:

提出了一种基于广域测量技术的AGC机组调节性能在线评估方法。首先提出了完整的AGC机组性能评估指标体系，将各类指标有效整合，从时间尺度和状态维度两个方面对AGC性能进行全面的评估。结合WAMS高采样率、高精度的数据特点，将AGC调节过程分成三段:快速控制段、考核控制段和超时控制段。不同的控制段采用不同的处理方法，从而有效减少计算量和存储量，满足在线快速评估的要求。该方法应用于湖南电网AGC在线评估系统，验证了该方法的正确性和有效性。

Abstract:

An online assessment method for AGC regulation based on WAMS is proposed. Firstly, this paper puts forward the assessment index system which integrates the indices in time scale and state dimension, thus makes a comprehensive appraisal for AGC units. Then responding to the high sampling rate and high precision characteristics of WAMS data, the control process of AGC regulation is divided into three segments:fast segment, assessment segment and time-out segment. Different methods are applied in different segments, so the calculation amounts and data storage can be efficiently declined to meet the requirements of fast online evaluation. The evaluation system has been applied in Hunan Power Grid and the results verify the feasibility and efficiency of proposed method.

Key words: online assessment of AGC regulation WAMS control performance standards sectional assessment
