matlab sps is used to build a simulink model of single-machine infinite-bus system, and based on the simulink model, simulation on effect of pss suppressing small disturbances low frequency oscillation is carried on, and some methods of improving power system transient stability are simulated, including avr and pss, short circuit cleared rapidly, fault current limiter and single-phase auto reclose. the study unifies the simulink model to realize matlab and vb seamless integration using the activex technology, and demonstrated the matlab simulation result with the vb contact surface. this method of matlab and vb integration can make up the matlab contact surface unfriendly flaw and offers a reference for the design for cai of power system analysis course.

After flow and transient stability calculating of the 330kV grid, we got the over-load and hazard lines set. Then we gained the redundant network needed to be built according to the increasing power supply and load in 2010. Adopting regradation step-by-step algorithm by which we can improve the calculation efficiency , we compared the validity of every line, deleted lines with low validity until no redundant line is in the network. At last we got the target network framework adopting the improved ant colony algorithm. Flow distribution, construction investment assessment and target framework of Gansu long-term planning all be considered, from the viewpoint of to be economic and reliability the feasibility of the improved ant colony algorithm is discussed.

This thesis is focused on the study of contingency screening method of power system. The main work fulfilled is as follows. 1 Various performance indexes which represent severity degree of contingencies are proposed and analyzed. These indexes are gotten system state before and after contingency clearing obtained by the means of time domain simulation. They can be computed conveniently and immediately and can meet the need of online transient stability analysis.
