Abstract

The invention discloses an on-line detection method for dynamic response of an excitation control system. The method comprises the following steps of: acquiring primary measurement signals by a voltage transformer; transmitting the primary measurement signals to an isolation measurement and signal superposition module, and synthesizing the primary measurement signals by the isolation measurement and signal superposition module to acquire measurement signals; transmitting the measurement signals to an excitation controller, and comparing the measurement signals with a target set value through the excitation controller to produce a comparison result; adjusting the output of a synchronous motor system according to the comparison result through the excitation controller; and detecting the dynamic response of the excitation control system according to the output of the synchronous motor system.

Description

technical field [0001] The invention relates to the technical field of excitation control, in particular to an online detection method for the dynamic response of an excitation control system. Background technique [0002] At present, the detection of the dynamic response of the generator excitation control system generally adopts the method of calculating the addition point of the reference voltage and superimposing the interference test signal, or the method of changing the target setting value. Such as figure 1 As shown, wherein, the interference test signal A comes from an external test device (not shown), and the target setting value deviation calculator 22 of the excitation controller 20 simulates the machine terminal voltage of the synchronous motor system 30 obtained by the voltage transformer 10 After the quantity is digitized, the interference test signal A is digitally superimposed, and the difference between the machine terminal voltage and the target set value ...
