Industrial enterprise power fault diagnosis system

Abstract

The invention discloses ''an industrial enterprise power fault diagnosis system''. The system can automatically discover almost all faults generated in production and power consumption processes of an industrial enterprise, automatically determine a fault position, and automatically analyze and diagnose a fault reason. The faults comprise enterprise distribution network disconnection, short circuit and grounding faults, a whole network voltage abnormal distribution fault, a whole network load current abnormal distribution fault, a whole network load distribution imbalance fault, a low power factor fault of whole network distribution, a whole network distribution harmonic abnormal fault, a whole network distribution line loss supernormal fault, and a whole network electric equipment fault. In order to realize automatic information monitoring, automatic information processing and automatic data transmission in a whole network, a microprocessor chip is embedded in an enterprise distribution network and is organically combined.

Description

technical field [0001] The invention belongs to the technology of informationization and intelligentization of power consumption in industrial enterprises; a microprocessor chip is embedded in each node of the power distribution network of the enterprise, so as to realize: detecting the electric power parameters of the node and the state of the local power grid, and calculating the power consumption operation Data, send and receive data to the nearest cable, achieve local informatization of each node, and then make the enterprise power distribution network informatization. Background technique [0002] The power network inside the factory is actually a local low-voltage power distribution network, which is connected to all production, living, and office buildings and rooms, and to all types of electrical equipment in the factory; Carry out on-line power consumption supervision; conventionally, only the power metering and readings are copied by partition, household, and time ...

Problems solved by technology

[0002] The power network inside the factory is actually a local low-voltage power distribution network, which is connected to all production, living, and office buildings and rooms, and to all types of electrical equipment in the factory; its distribution network is densely connected, and in the past, there was generally no Carry out on-line power consumption supervision; conventionally, only the electricity metering and readings are copied by partition, household, and time interval, and other operating parameters in the network are basically not systematically monitored; the electric energy is sent to the low-voltage distribution network of the factory through the distribution transformer , no one knows where the current goes and where the voltage drop is at all times. There is basically no management of distribution network cable leakage, line loss, and waste of electric energy. The power loss is very large, and various operating failures often occur. production impact
