Solid-state test platform and method for intelligent phase-change switch function test

Abstract

The invention relates to a solid-state test platform and method for an intelligent phase-change switch function test. The test platform comprises a main controller, a module I, a module II and a capacitor C, the main controller is respectively connected with the module I and the module II and is used for controlling the work of the module I and the module II; one end of the module I is connected with the output end of the transformer; one end of the module II is connected with the direct-current output end of the intelligent phase-change switch; the other end of the module I and the other endof the module II are connected with the capacitor C, and the module I, the module II and the capacitor C are connected in parallel; the module I is used for feeding excess energy on the capacitor C back to the power distribution network; the module II is used for controlling the magnitude and direction of current flowing through the intelligent phase-change switch; the capacitor C is used for energy supporting, filtering and smoothing. According to the invention, all unbalanced operation conditions can be simulated, the simulated unbalanced power is fed back to the power grid in a balanced manner through the test platform, the test in a power-consumption-free state is realized, and the influence on the main power grid is avoided.

Description

technical field [0001] The invention belongs to the technical field of equipment detection, and in particular relates to an expandable low-loss solid-state test platform for functional testing of intelligent commutation switches and a control method thereof. Background technique [0002] At present, the functional test platform of the intelligent commutation switch needs to be connected to the active load to perform the test, and there is a problem of active power loss; at the same time, after the load is connected, the active and reactive power of each phase load cannot be adjusted arbitrarily, and the unbalance degree cannot be adjusted. As well as the inability to perform multiple seamless transient load switching and other shortcomings. Such problems exist in the patent "a kind of phase change switch intelligent detection device". Therefore, how to overcome the deficiencies of the prior art is an urgent problem to be solved in the field of equipment detection technology...
