Analysis And Treatment Of Low Voltage In Distribution Network By Smart Substations

According to the national power grid planning,intelligent substation in electric power system safe production management in the process of operation maintenance is very important,and new intelligent substation in order to further highlight safeguard the safety of electrical equipment operation,adapt to the state grid corporation’s new intelligent safety power supply requirements,so to strengthen the process of in electric power system running and maintenance of all kinds of management,and to the equipment management procedure is optimized,ensure the power system can strengthen the optimization of management scheme can also strengthen the benign security and stability of power system,further satisfy the requirement of intelligent substation power supply at the same time improve the reliability and stability of the power station power supply and intelligence,automation,efficiency advantage.New power supply bureau to actively carry out low voltage control in power system,fully ready to area of low voltage user touch bottom and census,for the management of low voltage and optimize laid the foundation.New to intelligent substation to areas of low voltage problem diagnosis has carried on the detailed survey,carried out the analysis of the causes of technical level and management level,the comprehensive improvement of the problems of the low voltage,for different low voltage phenomenon seriously trying to comb,fully develop professional research analysis,adjust measures to local conditions of low voltage management approach and scheme is put forward.For low voltage in the process of operation and maintenance to take the effective management and technical measures to minimize power supply radius at the same time,reduce the voltage of three-phase unbalanced load,increase equipment patrol times,strengthen the dynamic monitoring frequency,adopted the movable voltage monitoring instrument,installation with a variety of technologies and solutions such as intelligent terminals,changeable to further reduce voltage lower voltage line loss,strengthen the voltage reactive power equipment operation maintenance and management,improve the ability of the voltage at the same time has made great progress,effectively improve the voltage quality is both the current and focus on the development,try our best to meet the expectations for the long-term development of power system.
