Abstract

The invention relates to a multi-service collaborative power distribution method, system and device and a digital power distribution terminal. A central power distribution terminal is arranged in a middle and low voltage power distribution network and is connected with a plurality of sub power distribution terminals, an intelligent circuit breaker and a plurality of power supplies, and the central power distribution terminal is connected with the sub power distribution terminals through a plurality of switches. According to the method, the fault position in the middle and low voltage power distribution network is determined according to the fault signal, and the closing mode of a plurality of switches in the middle and low voltage power distribution network is determined according to the fault position, so that the fault is isolated, and power supply is recovered through a plurality of power supplies. According to the scheme, the central power distribution terminal is arranged in the middle-low voltage power distribution network to monitor the fault of the power distribution network, and the operation of the power distribution network is maintained by using a plurality of power supplies, so that the cooperative management of high-low voltage power supplies can be realized, and the management efficiency of an electric energy system is improved.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a multi-service collaborative power distribution method, system, device and digital power distribution terminal. Background technique [0002] Electricity is one of the important resources to maintain the normal operation of people's production and life in our country. Therefore, maintaining the operation safety of electric power is an important task of the electric power management department. The management of electric energy includes the monitoring and management of the distribution network. Power management is to install multiple monitoring and control devices in the power grid to realize different functions such as control and monitoring. However, there are many monitoring and control devices in the current distribution network, and the workload of monitoring the monitoring and control devices is relatively large, resulting in a reduction in the efficiency ...
