Low-voltage diagnosis system based on real-time acquired data of intelligent electric meter

Abstract

The invention discloses a low-voltage diagnosis system based on real-time acquired data of an intelligent electric meter, which comprises a data acquisition module, a big data center, a data analysismodule and a data diagnosis module, and is characterized in that the big data center comprises a headquarters big data center and a provincial network company big data center. A data acquisition module, a big data center, a data analysis module and a data diagnosis module are designed, the data acquisition module is an intelligent electric meter, the data acquisition module is electrically connected with the big data center, the big data center is electrically connected with the data analysis module, and the data acquisition module and the data analysis module are electrically connected with the data diagnosis module. The data analysis module realizes fault pre-judgment and performs pre-judgment processing on faults which may occur in the future, a data framework of the data diagnosis module is divided into diagnosis support data, intelligent diagnosis data, operation and maintenance learning data and diagnosis application data, a low-voltage cause can be diagnosed intelligently, and then the probability of the low-voltage cause is further calculated.

Description

technical field [0001] The invention relates to the field of smart meters, in particular to a low-voltage diagnosis system based on actual data collected by smart meters. Background technique [0002] Voltage is an important indicator to measure power quality. All kinds of electrical equipment are designed and manufactured according to the rated voltage. These equipment will achieve the best results when they are operated under the rated voltage. If the voltage deviates too much from the rated value, it will have a bad influence on the user. Common electrical equipment in power systems are asynchronous motors, various electric heating equipment, lighting lamps, and household appliances that have increased in recent years. [0003] When the voltage is too low, the efficiency of the electrical equipment will decrease, affecting the quality and efficiency of production; when the voltage is too high, the life of the electrical equipment will be shortened. Excessive voltage off...

Problems solved by technology

[0003] When the voltage is too low, the efficiency of electrical equipment will decrease, affecting the quality and efficiency of production; when the voltage is too high, the life of electrical equipment will be shortened

Excessive voltage offset will not only affect the normal work of users, but also have adverse effects on the power system itself

Voltage reduction will increase the power loss and energy loss in the network. If the voltage is too low, it may endanger the stability of the power system operation; when the voltage is too high, the insulation of various electrical equipment may be damaged.
