Abstract

Abstract:

Firstly, the development and present situation of theoretical study and engineering application of the unified power flow controller （UPFC） at home and abroad were introduced. Then, the constraints in developing Nanjing Western grid were described in detail, such as limited transfer capacities of power imported channels, unbalanced power flow distributions and so on. Through the comparison with other convention solutions, the feasibility, necessity and inevitability of UPFC applied in Nanjing Western grid to improve the systems reliability and transfer capacity were investigated. Through the analysis and calculation, it is found that the application of UPFC not only can effectively control power flow, enhance the transfer capacity of the existing power grid, which can avoid constructing city-crossed cable channel with huge investment and difficult construction； but also can be well adapted to the changes of power grid frame in the future. Therefore, the application of UPFC in Nanjing Western grid or even Jiangsu grid in the future can prominently improve the transfer capacity, utilization efficiency and running security of power grid, which can achieve good economic and social benefits.

Key words: unified power flow controller （UPFC）, Nanjing Western power system, transfer capacity, operation reliability
