Embodiment

[0034] figure 1 It is a schematic diagram of the module composition of the cascaded SVG system and the controller performance test platform in the embodiment of the present application.

[0035] The cascaded SVG system consists of two parts, the SVG controller and the SVG main circuit. The controller performance test platform of cascaded SVG system consists of three parts: SVG controller, level adapter board, and RTDS real-time simulation model. The level adapter board is composed of a resistor voltage divider circuit and an optocoupler circuit, and realizes the matching of the signal level between the SVG controller under test and the RTDS. The RTDS real-time simulation model includes the SVG main circuit real-time simulation model and the power grid real-time simulation model.

Abstract

The invention relates to a controller performance test platform of a cascaded SVG platform. The test platform comprises an SVG controller, a level adaptation board and an RTDS real-time simulation model; a signal of the SVG controller is connected to a board card of the RTDS real-time simulation model via the level adaptation board; the level adaptation board comprises a resistance voltage division circuit and an optical coupling circuit, and is used to match the signal level between the SVG controller and the RTDS real-time simulation model; and the RTDS real-time simulation model comprises an SVG main loop real-time simulation model and a power grid real-time simulation model. A real-time simulation technology is used, an RTDS is used to establish a hardware in-loop system of the RTDS real-time simulation model and the SVG controller, and the technical problems that a present SVG controller performance test method is limited in test capability, hard to simulate the condition and incomplete in test functions are solved effectively.

Description

technical field [0001] The invention relates to the technical field of real-time digital simulation of electric power systems, in particular to a controller performance testing platform of a cascaded SVG system. Background technique [0002] Static var generator SVG is an important technical branch in the field of reactive power compensation, and plays an important role in power system stability and economic operation. Cascaded SVG has many advantages such as small size, low cost, modularization, fast response, low harmonic voltage output, separable phase control, no multiple transformers, etc. , Harmonic control, and power improvement are more and more widely used. [0003] The cascaded SVG system consists of two parts, the SVG controller and the SVG main circuit. The SVG controller is the control core of the cascaded SVG system. With the promulgation of the standards and specifications of the relevant dynamic reactive power compensation device, the requirements for the c...
