Research On Distributed Stability Control Device In Jinshan Power Plant

The power system consists of a number of units,including transmission lines,transformers,generators,combined electrical equipment.Power system is a huge system,distributed in vast areas,the main role is to provide customers with high quality electrical energy.The precondition of all this is that the power system can run stably and safely.At present,different countries and regions have different power system distribution,and the control system is also very different.Distribut ed control system is a new control system.The distributed control system can be applied to a single plant station,and can also be networked into a large area control system.Need to be able to adapt to transient and s teady-state control when used.In this paper,a distributed stability control device is desi gned for Jinshan power plant,Jindong No.1 line,Jindong 2 line and two spare lin es.When line fault tripping or line overload,pressing device according to the state control and strategy table at present,take measures to cut the mountain of the units,to ensure the safe and stable operation of power grid.
