Abstract

The invention belongs to the railway electric power technology field and especially relates to a control platform of back-to-back experiment testing used for a railway power regulator power unit. Thecontrol platform comprises a back-to-back control cabinet. A control chassis is arranged in the back-to-back control cabinet. The control chassis is connected to a first power unit to be tested and asecond power unit to be tested. Two ends of the first power unit to be tested are connected to an output end of a boosting transformer. Two ends of the second power unit to be tested are connected tothe output end of the boosting transformer. There are several current Halls and electric reactors. An input end of one current Hall is connected in series with one electric reactor, and then is electrically connected to the boosting transformer, the output end of the first power unit to be tested and the output end of the second power unit to be tested. Output ends of the plurality of current Halls are electrically connected to the control chassis. The control platform can be simply operated and can effectively and rapidly test each power unit. An optical fiber is used to realize connection ofthe control chassis and the power units. And an anti-interference capability of an apparatus is increased.

Description

technical field [0001] The invention belongs to the field of railway electric power technology, and relates to a test device for testing the full power of a power unit of a railway power conditioner (RPC) before installation, in particular to a control for the towing test of the power unit of a railway power conditioner The platform is suitable for full power testing of bidirectional back-to-back power unit parallel RPC module pairs. Background technique [0002] The railway power conditioner RPC has the ability to control the two-phase active power, reactive power and harmonic current of the substation. The unique feature of the railway power conditioner is that it can directly realize the transfer of active power while compensating for reactive power, and it also has the function of source filtering, which is more powerful. In particular, high-speed railway electric locomotives mostly use AC drive and PWM rectification. Simple SVC has limited effect on balancing system vo...
