Study On Relay Configuration About Parallel Capacitor In High Voltage

With the continuous expansion of the scale of power grids, it need more and more reactive compensation devices. Parallel capacitors is the most economical and practical reactive compensation devices, therefore, parallel capacitors in recent years have been the development by leaps and bounds. 2007 substation capacitors for the transport of Taiwan in 2004 growth has more than doubled, and capacitors also greatly enhance the capacity of the current application of the maximum capacity of capacitors for 60 Mvar. However, the capacitor production processes and no corresponding keep up, leading to the accident capacitors, not only caused economic loss, but also reduce the power grids in southern Hebei Power quality. Based on the configuration capacitors selection and installation carried out in-depth analysis and through the power grid in southern Hebei capacitors extensive research, summed up the currently existing problems and improve methods for future selection of equipment and protection configuration Provides a theoretical guidance.
