Key Technology of Multifunctional Wide Area Synchronous Phasor Measurement Terminal Device in Distribution Network

In the context of the construction of the energy Internet, the distribution network has an increasing number of intermittent and uncertain distributed power generation, more changes in operation modes, obvious power electronics, and diversified and interactive loads. This series of new The form brings challenges to the perception and reliable operation of the distribution network. The application of wide-area synchronous phasor measurement technology to design miniature, low-cost, multi-functional terminal devices to improve the perception and coordination and control of distribution network operation status will become the equipment support for the safe and stable operation of the regional energy Internet. In response to the application requirements of stable, high-precision, low-cost real-time monitoring devices and systems in the distribution network, the application of synchronous phasor measurement technology to the distribution network can comprehensively improve the appreciable, measurable, and controllable capabilities of the distribution network, Will be an inevitable trend in the development of the future distribution network. The multifunctional terminal device of distribution network based on synchronous phasor measurement information designed in this paper flexibly uses synchronous phasor measurement information technology, which can effectively improve the reliability of the distribution network and has high engineering application promotion value.
