Problems solved by technology
Most power management systems only collect and record multi-power data, but do not perform power quality analysis and fault warning
At the same time, high-frequency data collection will generate a huge amount of data transmission. The power management system on the market cannot process big data at the same time, resulting in the loss of a large amount of important data.

Embodiment
[0039] The urban rail transit electric energy management system of the embodiment of the present invention is based on the method of "distributed collection and centralized management". The collection of electric energy data adopts the method of collection step by step. The current and voltage signals are collected at high frequency, analyzed and stored locally, and then the power data of each high-frequency power collection terminal is collected to the information collection server, and finally stored in the network storage, and displayed and output through the power management platform server. The management platform server can also obtain the historical electric energy data in the network storage according to the demand, so as to ensure the smooth information interaction of each communication link.
[0040] Please refer to figure 1 As shown, an urban rail transit power management system includes a high-frequency power collection terminal, a communication switch, an informat...

Description
technical field [0001] The invention relates to the technical field of electric energy management systems, in particular to an urban rail transit electric energy management system and method. Background technique [0002] At present, rail transit in major cities in China is developing rapidly, but there are still many problems in electrical management. On the one hand, electrical faults occur from time to time, so it is urgent to comprehensively improve the safety management level of electrical operation; on the other hand, urban rail transit consumes a lot of electric energy. must do. However, for now, how to improve the electrical operation safety management level and energy efficiency management level of urban rail transit is a technical problem that the industry has been difficult to overcome. [0003] Most urban rail transit accidents are caused by electrical faults, which will bring huge economic losses on the one hand and negative social impact on the other. One of...
