Abstract

The invention, which relates to the technical field of power systems, discloses a detection system of an excitation regulator of a generator so that a problem of error introduction into the dynamic performance detection process can be solved. The detection system is composed of an excitation regulator device, a simulation interface device, and a real-time simulation device. The real-time simulation device is connected to the excitation regulator device through the simulation interface device. The excitation regulator device consists of an excitation regulator main control system and an excitation regulator analog sampling board connected with the simulation interface device and the excitation regulator main control system respectively. The excitation regulator analog sampling board outputsa low voltage signal collected from the simulation interface device to the excitation regulator main control system directly.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a detection system for a generator excitation regulator. Background technique [0002] The dynamic performance of the excitation regulator of the generator has an important influence on the voltage stability of the power plant and the entire grid. Especially under DC island conditions, the impact of power plant voltage fluctuations on the stability of the island system is more direct and significant than that of power plants in conventional AC systems. Therefore, it is necessary to do a good job in the dynamic performance testing of DC island generator excitation regulators. Before it is actually put into use, the control characteristics of the island system under different working conditions and fault conditions are studied to check whether it can meet the requirements of stable operation. [0003] Due to the large number of related equipment and complex control character...
