The high energy consumption of municipal street lighting system is not consistent with the concept of building a conservation oriented society in our country. Therefore, the construction of energy-saving municipal street lighting is imperative. The compensation technology of municipal street lighting electrical system is an effective means of energy-saving transformation. Firstly, this paper analyzes the application status of compensation technology of municipal street lighting electrical system, and puts forward some solutions for the existing problems, so as to provide some reference for the application of compensation technology of municipal street lighting electrical system.
