Abstract

The invention discloses a 10 kV voltage class STATCOM testing platform and testing method. The 10 kV voltage class STATCOM testing platform comprises a testing circuit, an adjustable load, a testing instrument, a signal collection bus and a host computer system. According to the 10 kV voltage class STATCOM testing platform and testing method, the host computer system is used for controlling the on-off states of a high-voltage circuit breaker and a low-voltage circuit breaker in the testing circuit, meanwhile, a voltage disturbance generator is controlled to output different disturbance voltages, furthermore, idle work of the adjustable load and work of a harmonic generator device are controlled to be in a reactive-power output or harmonic wave output state, and the performance of STATCOM products which are tested is analyzed through the mode that the testing instrument observes the output of the STATCOM products which are tested; the 10 kV voltage class STATCOM testing platform and testing method are based on a power electronic device of a modularization cascade connection type structure, the structure is simple, and the control is flexible; in addition, the 10 kV voltage class STATCOM testing platform and testing method take all operational conditions of the STATCOM into overall consideration, the adaptive capacity and the compensation effect of the STATCOM which is tested are tested comprehensively, and therefore testing results are comprehensive and dependable.

Description

technical field [0001] The invention belongs to the field of electric equipment performance detection, and in particular relates to a STATCOM detection platform and a detection method with a voltage level of 10kV. Background technique [0002] With the rapid development of modern industry and design needs, the nonlinear and impact loads in the power grid are increasing, which has a great impact on the power quality, and at the same time, it also puts forward the reliability and stability of power supply. increasingly severe challenges. Due to the excellent performance and incomparable advantages of the flexible AC transmission system (FACTS) in improving power quality, FACTS has also been widely used in power grids. As one of the core equipment of FACTS - STATCOM (Static Synchronous Compensation device), it has good compensation performance, can quickly compensate the reactive power of the system, effectively suppress voltage fluctuations and flicker, change the three-phase...
