摘要（英）：

The invention provides a static var generator (SVG) apparatus detection system based on a real-time digital simulator (RTDS). The SVG apparatus detection system comprises a RTDS apparatus and an amplifier, wherein the RTDS apparatus is connected with a SVG apparatus and the amplifier and is used for simulating a power system, outputting power grid signals of the power system to the amplifier, receiving pulse width modulation PWM signals fed by the SVG apparatus, changeing the running points of the power system and analyzing the change cases of the power system under the effect of the PWM signals fed by the SVG apparatus so as to detect the SVG apparatus; and the amplifier is connected with the SVG apparatus and is used for receiving, amplifying and transmitting the power grid signals of the power system to the SVG apparatus. In the case that the operation of a power grid is not influenced, the SVG apparatus detection system may simulate the real operation conditions of the power system, comprehensively detect the response characteristics of the SVG apparatus according to a correlative technical standard, timely find the technical defect of the SVG apparatus, provide striving direction and technical guidance for the technical reconstruction of the SVG apparatus, and has significant meaning to stabilization of power grid voltage after wind power is accessed.
