Embodiment Construction

[0044] For example, enterprise distribution network power fault diagnosis.

[0045] The accompanying drawings in the description show an actual industrial enterprise with 5 workshops, in which the management of power consumption is implemented by each workshop itself.

[0046] The power consumption management of the third workshop is implemented based on the No. 3 node. At 10:00 a.m. on a certain day, the power consumption administrator found that the power consumption data of the workshop at 10:00 was much larger than that at 9:00, and it was also larger than the power consumption at 10:00 yesterday. Many, administrators start to diagnose.

[0047]He checked the power consumption of the secondary nodes 31, 32, and 33 of the No. 3 sequence at 10:00, and found that the power consumption of 31 and 32 was normal, and the power consumption of 33 at 10:00 increased a lot, and found that 33 was under load at 10:00 The current also increases a lot, which verifies the problem at 33; ...

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 ...
