A cps-based agc logic control system and method

Abstract

The invention particularly relates to an AGC (Automatic Generation Control) logic control system and method based on a CPS (Control Performance Standard). The implementation of the method comprises the following steps of 1) carrying out time sequence real-time rolling linear filtering processing on original data, such as an area control error ACE and a frequency deviation delta f; based on a CPS1, introducing different control threshold values n to adjust an ACE signal, and combining a further correction of amplitude control of the delta f so as to form a logic control module facing to the CPS1 standard; 2) based on a CPS2, setting different control threshold values m to check the ACE signal, and selecting a dynamic calibration method to realize dynamic cooperation between the ACE signal and the delta f so as to implement a logic control module facing to the CPS2 standard; 3) adopting a priority coordination control mechanism to carry out coordination processing on the CPS1 logical control module and the CPS1 logical control module so as to complete integrated optimal control of the AGC signal. According to the AGC logic control system and method, the operating efficiency of an AGC controller is remarkably improved, and the frequency control performance and the operating economy of the system are enhanced.

Description

technical field [0001] The invention relates to the field of power system and automation, in particular to a CPS-based AGC logic control system and method. Background technique [0002] Automatic generation control (AGC), as the main means of controlling the power and frequency of the interconnected power system, not only needs to be able to maintain a constant system frequency and tie-line exchange power, but also needs to follow certain rules to meet the comprehensive requirements of system dynamic characteristics and regulation performance. The domestic traditional AGC control strategies are mainly formulated based on the A1 / A2 standard. After the introduction of the CPS standard, these control strategies are no longer applicable. At present, there are two main improvement ideas, one is to carry out adaptive improvement of CPS standard on the basis of the original control strategy, and the other is to set aside the shackles of A standard and re-establish AGC control strat...
