Abstract

The invention provides an RT-LAB-based low-voltage APF hardware-in-the-loop simulation test method and system. The method comprises: collecting a system parameter and a signal of a digital model of alow-voltage APF running in real time in a real-time digital simulation machine; sending the system parameter and signal to a tested APF controller; and sending a control command and a pulse signal, generated by the tested APF controller based on the system parameter and the signal, to the low-voltage APF digital model running in real time in the real-time digital simulation machine. According to the invention, closed-loop control between the real-time digital simulation machine and the tested APF controller is realized; a technical problem that the actual performance of the actual APF controller can not be checked or the cost is high when the software full-digital simulation or field filtering test is employed is solved; and thus the actual performance checking of the actual APF controlleris realized and the test cost is lowered.

Description

technical field [0001] The invention relates to the field of power equipment testing, in particular to an RT-LAB-based low-voltage APF hardware-in-the-loop simulation testing method and system. Background technique [0002] With the rapid development of the power system, reactive power and harmonic loads increase rapidly. In order to deal with these problems, more and more active power filters (Active Power Filter, APF for short) are introduced in the power system for reactive power compensation and harmonic governance. The power system is a complex dynamic system. The performance of APF equipment is directly related to the stable operation of the power system. Mistakes in the action or performance of the equipment may cause serious consequences and even major economic losses. Therefore, APF equipment must be As close as possible to the actual operating environment of the power system, undergo rigorous testing. [0003] At present, the simulation test method of APF equipme...
