Research on the transmission line construction risk control and management information system

Electric power industry is an important basic industry of national economy, due to the important r support for national economy development and guarantee for people's living standards. With the rapid development of national economy during the past twenty years, the development of Chinese electric power industry have maintained a rapid speed, and the average annual growth rate was up to 8.1%. As far as the beginning of 2007, 330 KV transmission line over 15000 kilometers has been built in our country, 500 KV lines have almost up to 50000 kilometers.[1]It can be seen that China will be the largest electric power construction market of all the world in the future for a period of time. Transmission line projects is characterized as high cost, long construction period, complex technology and involving multiple units, therefore the risk of power construction project is much bigger compared with other construction projects, besides, the risk management of electric power construction project in our country is still in its infancy. With the electric power system reformation,factory departs from the nets, our country's electric power construction project investment is diverse, great changes also have taken place in enterprise ownership structure, electric power construction project risk management has gradually drawn the attention of the project participants[1-3].
