Design of Power Supply System for 10kV Smart Switch Based on PV Technologies
Abstract:
With the rapid development of the smart grid in our country, we need many 10kV smart switches which can protect the safety of the line and complete the reasonable scheduling of the electricity load. In order to realize the reliable power supply for 10kV smart switch, power supply system based on photovoltaic cell technology is designed. In this paper, firstly, we have a brief introduction about the 10kV smart switch. Secondly, composing and principle of the power supply system is introduced. And then, principle of the energy harvesting converter main circuit is analyzed in detail. Then, the MPPT method of the photovoltaic cell based on impedance matching is studied. Test show, the power supply system is suitable for 10kV smart switch measurement and control.
