A power distribution system for distributed energy supply system

Abstract

The invention discloses a power distribution system for a distributed power supplying system. The power distribution system comprises an I-segment base and an II-segment bus. The I-segment bus is connected with the II-segment bus through a grid-connected circuit breaker. The power distribution system further comprises a power distribution controller and n wire outlet loops. Each wire outlet loop comprises an I-segment sub wire outlet segment which is connected with the I-segment bus, an II-segment sub wire outlet segment which is connected with the II-segment bus, a total wire outlet segment,and a connecting segment for connecting the I-segment sub wire outlet segment with the II-segment sub wire outlet segment. The I-segment sub wire outlet segment and the II-segment sub wire outlet segment are respectively provided with a sub wire outlet circuit breaker. Each circuit breaker is in bidirectional communication connection with the power distribution controller. A power distribution program is configured in the power distribution controller for selecting a wire outlet loop with a corresponding load property according to a current power supplying mode for supplying power to the powerdistribution controller, and switching off the wire outlet loop which is unsuitable for the current power supplying mode. The power distribution system performs power distribution according to an electric load property, thereby improving safety, reliability and economic performance in operation of a power generation set.

Description

technical field [0001] The invention belongs to the technical field of power energy distribution, and in particular relates to a power distribution system and a power distribution method. Background technique [0002] With the development of economy and technology, the establishment of a distributed energy supply system integrating cooling, heating and power supply in large compound centers has begun to be applied. The controllers of large and medium-sized thermal power plants do not consider the load form, but only consider the size of the electric load. There are various large-scale enterprises and manufacturers promoting it, and their power supply technology is relatively mature; however, for the power supply of small distributed energy supply systems, small power The generator set is used to prepare for the situation that the mains power cannot be supplied normally. Due to the small capacity of the low-power generator set, the ability to resist load changes is weak, so n...
