Application Research Of Smart Distribution Grid In Gaomi Power Grid

On May21,2009to22, the representative from the relevant international organizations and the world21countries and regions of the government departments, industry organizations electric power enterprises, research institutions, design units, manufacturers, universities, financial institutions, participated in the Chinese Beijing held "2009International Conference on UHV transmission technology", in the meeting for the first time put forward the target of China State Grid Corp construction of strong smart grid. Strong smart grid is with strong grid as the basis, with communication and information platform as the support, with intelligent control as the means, covers the hair, transmission, distribution, change, electricity and scheduling at each link, covering all voltage levels, will power flow, information flow, business flow effective fusion, is a kind of the new mode of modern power grid. Distribution system is an important foundation for one of the strong smart grid and the six part, the construction of its distribution automation will be presented along with the strong smart grid concept has produced a new impetus.Give full consideration to the different social environment, grid around the various conditions of the actual, the China State Grid Corp in2009196, the requirements of smart distribution grid, construction should follow the local conditions, the social economic development of power quality requirements, application status, the construction of communication system information application system deployment planning and promotion, design reasonable, make the distribution network a grid structure, communication mode in power equipment, and master station etc. to meet the construction requirements, the implementation of intelligent network construction by stages. In this paper, to be a pilot, step by step implementation principle, situation of distribution network structure, the company building area of smart distribution grid connection mode of a device, such as a detailed analysis of the present situation of the protection; analysis of carding operation mode, the configuration of distribution network, communication mode, all kinds of information application system, fully combined with the actual situation of local distribution network, develop the smart grid construction overall planning objectives and detailed construction reforming scheme, mainly includes the construction of grid, the main station, FA, terminal etc..Smart distribution grid construction company will be high density, with a strong distribution network a network construction as the foundation, through the construction of safe and reliable, convenient and intelligent power network to realize the model of distribution network is efficient and practical, strong and smart. Through the construction of smart distribution network, automatic recovery of power supply to achieve fast positioning line fault and discrimination, complete the fault section automatic isolation and non fault section of the remote control system operation mode change, uninterrupted monitoring of distribution network real time running state, effectively reduce the outage time, guarantee power supply, further improve the reliability and quality of power supply the company, to create a quality brand, promote the good social image of the company.
