Problems solved by technology

[0009] However, the preventive measures and troubleshooting of existing technologies are often relatively simple, and most of them use the distribution automation master station system for remote monitoring and operation, and the practicability is not good, and there are no complete treatment measures for some special cases
When realizing the preventive control of the distribution network, most of them only collect data and predict data in real time for the current distribution network, without effectively combining the defects of each device itself, relevant historical information and the probability of failure of similar equipment, and not considering the equipment in the network. The position in the topology, which is likely to cause preventive reconstruction only by relying on the evaluation of operating parameters in the case of short-term low voltage violations, and cannot pre-set various indicators, cannot store current network topology information, and cannot quickly Effectively save time for preventive control treatment

Abstract

The invention relates to a prevention, control and fault handling method and system for a power distribution network. The prevention, control and fault handling system for the power distribution network comprises a uniform-control platform, an information acquisition unit and a prevention and control unit, wherein one end of the uniform-control platform is connected with the information acquisition unit, the other end of the uniform-control platform is connected with the prevention and control unit, the prevention and control unit is used for predicting the abnormal operating state of devices in the power distribution network in a short period of time in future, and the prevention and control unit comprises a second index calculation module used for setting an index in advance according to the information of the devices in the power distribution network and the information of a network topology and storing the information of the topology so that data support can be provided for a fault handling unit. The prevention, control and fault handling method and system for the power distribution network have the advantages that the practicability is high, threshold crossing can not occur easily in a short period of time, time of prevention and control handing is effectively saved, energy is saved, and the probability of occurrence of faults is lowered.

Description

technical field [0001] The invention relates to a control and processing method and system of a distribution network, in particular to a method and system for preventive control and fault processing of a distribution network. Background technique [0002] A variety of distribution network control and processing methods are disclosed in the prior art, most of which use the distribution automation master station system for remote monitoring and operation, and the practicability is not good, and there are no complete processing methods for some special cases measure. [0003] Centralized and distributed coordinated distribution network self-healing control method, signal processing and control strategy generation are self-adaptive, the control process can be completed automatically without manual intervention, and the relay protection device and protection control device, switch and intelligent The action behavior of switches and safety automatic devices includes two steps of ...
