Abstract

The invention discloses a performance testing system of a large-capacity reactive power dynamic compensating device, comprising a detected reactive power dynamic compensating device, wherein the performance of the dynamic compensating device is to be detected. The performance testing system is characterized by also comprising an electric energy quality analyzer, a high-voltage switch cabinet, an active load and an inactive load, wherein the active load is externally connected with a power grid by the high-voltage switch cabinet and is connected with the dynamic reactive power compensating device in parallel; and the inactive load provides adjustably capacitive or inductive reactive power having the property opposite to the property of the reactive power generated by the detected reactive power dynamic compensating device. The performance testing system has the beneficial effect that a full load test and a system performance test are carried out for the large-capacity reactive power dynamic compensating device by smaller-capacity power grids in factories or laboratories. The quality problem possibly existing in the device is easier to find to ensure that the device is successively put into operation once on the scene.

Description

technical field [0001] The invention relates to a system for testing the performance of a large-capacity reactive power dynamic compensation device in a small-capacity power grid, and belongs to the technical field of power systems. Background technique [0002] At present, in order to improve power quality, reduce line loss, and save energy and electricity, large-capacity reactive power dynamic compensation equipment [0003] More and more applications are placed in the transmission and distribution network of the power system. At present, large-capacity reactive power dynamic compensation equipment [0004] There are mainly static var compensation devices based on thyristor valves (SVC—static Var compensator) and [0005] Advanced Static Var Generator Based on Power Transistor (ASVG-Advanced Static Var Generator) [0006] It is also called a static condenser (STATCOM-Static Condenser), and their common characteristics are [0007] The reactive power capacity that can b...
