Nanchang Chang Dong Area Grid Security And Stability Control System Feasibility Study And Application

With the expansion and development of the power system, regional networkingand conduct a wide range of energy transfer, power grid security and stability controlsystems have become increasingly demanding. In China, many traditional localcontrol mode, such as a simple line fault interlock cutting machine, load sheddingdue to its technical performance backward and poor economic shortcomings havebecome increasingly unsuited to the security and economy of the requirements ofmodern large power grids. Development of intelligent, multi-regional security andstability is an urgent need for emergency control device safe and stable operation ofmodern power grid. The basic idea is that when the emergency control grid by theemergence of large disturbances emergency, perform cutting machine, loadshedding and other emergency control measures to restore the system to normaloperation. Installation of security and stability in the power system emergency controldevices to improve power system security and stability, prevent accidents gridstability, a large area of effective measures to prevent blackouts. Firstly, thefeasibility study report Nanchang Changdong Area grid security and stability controlsystem is analyzed, and finally Changdong Area to build a stable systemconfiguration and application summary. Results of research results provide for thefuture security and stability in Jiangxi control system design specifications andtransformation experience for design, operation provides a useful reference.
