Abstract

The invention provides an ACE (Area Control Error) segmentation control method and device based on a CPS (Control Performance Standard). The method comprises the following steps: calculating the ACE of a current control zone i, wherein the ACE is equal to 20Bi[Delta]f+[Delta]PC; determining a control segment where the calculated ACE is positioned, wherein the ACE corresponding to the center line of the control segment is 10Bi[Delta]f, and the control segment comprises a dead zone, a normal zone, an auxiliary zone and a coordinated zone; and on the basis of the control segment where the ACE is positioned, regulating the practical power of a generating set in the control zone i. By use of the method and the device, the problem of manual factor interference in a control segment division way set on the basis of the experience of workers can be avoided, system resources can be optimized, and the use ratio of generating resources is improved.

Description

technical field [0001] The present invention relates to the field of electric power control, in particular, to an ACE (Area Control Error, area control deviation) segmented control method and device based on CPS (Control Performance Standard, control performance standard). Background technique [0002] The standard for characterizing the quality of power products is three main indicators such as frequency, voltage and waveform. In steady state, the frequency of the same AC power system is consistent. When the power generation output of the power system is out of balance with the system load, the frequency will change accordingly. Therefore, the frequency is the most sensitive and can directly reflect the operating parameters of the active power balance of the power system. Based on this, ACE is introduced in the related art as a parameter reflecting the active power balance of the power system. Its expression is: [0003] ACE=10B·Δf+ΔP C [0004] Where: B is the freque...
