ABSTRACT
With the repeated transformation and upgrading of China's high-voltage power grid, the power infrastructure has been significantly improved, providing a strong support for economic development. In the new round of high-voltage power grid transformation plan, the construction of distribution automation system and the reliability of power supply environment become the key. Reactive power compensation, as an important means to improve the voltage quality and power supply reliability of the high-voltage power grid, plays an important role in reducing the power loss and improving the power factor.
In this paper, with the ADE7953 controller as the core, the electrical design of the high voltage power grid reactive power compensation device is studied. Through the real-time sampling of three-phase current and voltage data, the ADE7953 data analysis and processing, determine the capacity and method of reactive power compensation, realize the dynamic input and resection of capacitor group, so as to optimize the reactive power and reduce the economic loss of enterprises and individuals. This study has important theoretical and practical value for improving the power supply quality and economic efficiency of high-voltage power grid.
