Embodiment Construction

[0036] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] In the STATCOM system, limited by technical issues, 3300V IGBT or 4500V IGBT switching devices are usually used. The number of chain link units in the chain link is small, and the bus voltage balance control is relatively easy to achieve. However, the AC port of the chain link The voltage requirement is high, and ordinary circuit breakers cannot be used to realize the bypass, so it is necessary to use a customized bypass switch with a relatively high port voltage to realize the bypas...

Abstract

The invention provides a STATCOM (Static Synchronous Compensator) chain element unit bypass device and a control system. The bypass device is arranged in a chain element unit and comprises a circuit breaker with an electric operating mechanism. The input end and the output end of the circuit breaker are respectively connected with two AC ends of an H-bridge circuit of the chain element unit. When the circuit breaker is closed, the chain element unit can be bypassed from the STATCOM. The bypass device is simple in structure, few in components, low in cost, and convenient in mounting, operation and maintenance; the volume of the STATCOM can be reduced; and the power density and the reliability of the chain element unit are improved.

Description

technical field [0001] The invention relates to the technical field of dynamic reactive power compensation in electric power systems, in particular to a STATCOM chain link unit bypass device and a control system. Background technique [0002] STATCOM (Static Synchronous Compensator, Static Synchronous Compensator) is an important part of the flexible flexible AC transmission system (FACTS) in the field of dynamic reactive power compensation technology. STATCOM is connected in parallel in the power grid, which is equivalent to a controllable reactive power supply. Its reactive current can quickly follow the change of load reactive current, automatically compensate the reactive power required by the grid system, and realize dynamic control of grid reactive power. Reactive power compensation. [0003] STATCOM adopts H-bridge cascaded chain structure, which includes multiple cascaded link units, and each link unit adopts H-bridge topology. The bypass of the chain link unit tha...
