Implementation method of multi-physical model based on dynamic voltage recovery device

Abstract

An implementation method of a multi-physical model based on a dynamic voltage recovery device is based on the dynamic voltage recovery device and can collect physical information of the dynamic voltage recovery device, including length, width, height, installation geographic position and the like of the dynamic voltage recovery device and can process and acquire digital information such as voltage, current, active power, reactive power, humidity and temperature. An operator gives an operation state evaluation condition of the dynamic voltage recovery device according to an evaluation calculation result and a historical data model, and controls the dynamic voltage recovery device to carry out voltage control of the intelligent power grid, so that the operation state of the device can be accurately mastered in real time through the equipment evaluation result. More reliable digital support is provided for equipment operation, so that the operation and maintenance efficiency of a dynamic voltage recovery device in a modern power transmission/distribution network is improved.

technical field [0001] The invention belongs to the field of smart grids, in particular to a method for realizing a multi-physics model of a dynamic voltage recovery device. Background technique [0002] With the development of smart grid, it is necessary to evaluate the operation status and product life of power equipment in the whole life cycle, so as to help operators operate and maintain the equipment. [0003] Dynamic voltage restorers (dynamic voltage restorers, DVR) are mainly used in distribution networks to solve problems such as voltage swells, sags, and short-term interruptions in distribution lines, and have been more and more widely used in modern power distribution networks. However, due to the scattered installation of dynamic voltage recovery devices and the complex internal structure of the equipment, it brings a lot of inconvenience to the operation status evaluation and maintenance of dynamic voltage recovery devices, which will limit the application range...
