Problems solved by technology

[0003] In the traditional power grid, based on the low-voltage distribution network, micro-grid and energy router dynamic parameter measurement, online identification and transient process lack analysis technology and low-cost hardware monitoring device based on cloud computing, Internet of Things and power big data, Although the synchronous vector measurement device of 110kV and above main substations can be used for some functional applications, its complex structure and high cost characteristics of redundancy make the dense deployment at the low-voltage distribution network level unbearable
Not only that, but the frequency accuracy, sampling speed and core control algorithm of the traditional synchronous vector measurement device are also difficult to meet the massive data processing requirements of low-voltage distribution network side situation awareness, dynamic parameter measurement and transient analysis, and thus cannot adapt to the energy Internet framework. Requirements for power quality governance, real-time monitoring and scheduling of regional energy, and energy transaction management
At the same time, with the gradual development of the energy Internet, a large number of distributed new energy sources are connected to the grid, and it becomes more difficult to lock the source of power failures.
