Problems solved by technology

A lot of PMU devices based on GPS have been developed, but most PMU devices in European and American countries only measure electrical phase angles rather than power angles; some PMU devices developed in my country can directly measure generator power angles, but their installation and use are not flexible, and higher cost

Embodiment Construction

[0032] Below in conjunction with accompanying drawing, structure and principle of the present invention are described in detail:

[0033] Such as figure 1 and figure 2 As shown, the hardware of the wide-area measurement system based on the mobile Internet-based low-voltage network includes smart chargers, smart phones, databases, servers, communication base stations, and GPS satellites.

[0034] The wide-area measurement system of the low-voltage network based on the mobile Internet is mainly used in the low-voltage distribution network system. The wide-area measurement system is mainly derived from the time synchronization and space wide-area requirements of the power system, and uses the GPS clock synchronization of the global positioning system to measure the state of the wide-area power system. The mobile Internet-based wide-area measurement system uses a specially designed mobile phone charger to measure and analyze electrical parameters such as voltage amplitude and h...

Abstract

The invention relates to a wide area measurement system and method of a low voltage network based on a mobile internet. Hardware of the wide area measurement system includes an intelligent charger, an intelligent mobile phone, a database, a server, a communication base station and a GPS satellite. The wide area measurement system and method are mainly applied to a low voltage power distribution network system. The electrical parameters, capable of reflecting the problems such as voltage abnormality and harmonic pollution, such as voltage amplitude, harmonic content and the like of the operation of a low voltage power grid are measured and analyzed by utilizing a specially-designed mobile phone charger. When the intelligent mobile phone is charged, data is uploaded to a mobile phone APP by virtue of a USB. Meanwhile, measurement device clocks of the whole network are unified by utilizing the global positioning system (GPS), and the voltage parameter at each measurement point of the low voltage power grid is measured and uploaded in real time. The real-time data is uploaded to the server by utilizing the mobile phone APP so as to be further analyzed and researched in the server.

Description

technical field [0001] The invention relates to a wide-area measurement system and method for a low-voltage network based on the mobile Internet. Background technique [0002] The wide-area measurement system is mainly derived from the time synchronization and spatial wide-area requirements of the power system. The global positioning system (GPS) clock is used to synchronize the state of the wide-area power system. According to the above two development requirements of the power system, the phasor measurement unit PMU and the wide area measurement system WAMS appeared. A lot of PMU devices based on GPS have been developed, but most PMU devices in European and American countries only measure electrical phase angles rather than power angles; some PMU devices developed in my country can directly measure generator power angles, but their installation and use are not flexible, and higher cost. [0003] With the vigorous development of the Internet in recent years, the popularity...
