Looped network control cabinet, power distribution network control system and power distribution network control method

Abstract

The invention discloses a looped network control cabinet. The looped network control cabinet comprises an industrial computer, a PLC controller and a plurality of interconnection switches. The invention also discloses a power distribution network control system for controlling a power distribution network system, the power distribution network system comprises a plurality of transformers, each transformer comprises a plurality of leading-out loads, the leading-out loads comprise adjustable leading-out loads and unadjustable leading-out loads, and the power distribution network control system comprises a plurality of transformer measuring instruments, a plurality of load switches and the looped network control cabinet. The invention also discloses a power distribution network control method. According to the looped network control cabinet disclosed by the invention, electrical parameter data of the transformers are received and processed by the industrial computer, and transfer control for the adjustable leading-out loads is intelligently realized in combination with the PLC controller and the interconnection switches. According to the power distribution network control system and the power distribution network control method, the electrical parameter data of the transformers measured by the transformer measuring instruments are received by the industrial computer, the overload conditions of the transformers are judged, the interconnection switches and the load switches are controlled by the PLC controller, and the overload of the transformers is eliminated.

Description

technical field [0001] The invention relates to the field of power distribution control, in particular to a ring network control cabinet, a distribution network control system, and a distribution network control method. Background technique [0002] Now for the low-voltage power distribution system, when there are more than three transformers for power supply, if one of the transformers is overloaded, the control cabinet adopts a simple logic control contact switch manually or relay to transfer part of the load, so that the transformer can run safely and stably . However, when the relay or PLC logical relationship is used to control the contact switch to transfer the load to deal with the overload problem of the transformer, the variability of the transformer load in this area cannot be considered, so some unnecessary operations will be caused, leading to misjudgments, resulting in Larger economic losses; low reliability and intelligence of the control of the distribution n...
