Research On The Field Operation And Application Of 110kV Mobile Substation In Jiaxing Power Grid

With the rapid development of science,technology and economy,the requirement of power supply quality and reliability is growing.Substation is a voltage transformation in power systems,receiving and distributing electrical energy,controlling the electricity flow and adjusting the voltage of electric power facilities,it contacts the power grids at all levels by transformer,and plays an important role on the safe and stable operation of power grid.Compared with conventional substation,110 k V mobile substation has become the new favorite of the current smart grid development.Its space is smaller,more compact and has a high degree of integration and intelligent level is high,flexible operation,easy to use,the installation of combination shortcut,short construction period,cover an area of an area small,etc,can greatly improve power grid emergency power and ability of disaster prevention and mitigation,and to ensure the safe and stable operation of power grid,at the same time to provide users with high-quality,reliable power supply.This article introduces the development background and application status quo of mobile substation,summarizes the basic characteristic of the mobile substation,and then for some difficult and dangerous point in the process of operation maintenance,puts forward the ideas and technical solutions to solve the problem,in order to improve the mobile substation subsequent operations management level.This article focuses on the contents that cover the ground construction,installation,debugging and acceptance,as well as the daily operation and maintenance,the way of transport,the introduced power,the safe distance control,the security arrangement,the reliable grounding,and the management of mobile substation and so on multiple levels of temperature and humidity.These contents can effectively improve the mobile substation operation effect and well solve the reconstruction of power grid in the process of power outage,load transfer,boost power grid emergency power and ability of disaster prevention and mitigation,and ensure the safe and stable operation of Zhejiang power grid.Found through research and application,the technical innovation,not only enriched the mobile substation operations research in the field of technology and management,etc,but also for the mobile substation safe and efficient use of accumulated some theoretical basis and operational management experience,to further improve the level of the operation of the mobile substation has strong guiding significance.
