Study, The Power System Electromechanical Transient Simulation And Design Of Parallel Algorithms And Component Program

The dynamic characteristics and the stability of power systems need to be carefully considered in power system design, planning, and its operation and control. Hence the electromechanical transient simulations are needed. The simulation of large-scale power system is generally time-consuming. And as the continuous augmentation of the scale of power systems, the computation work is increasing rapidly, and becoming more complex. On the other hand, the applications such as on-line dynamic security assessment and transient stability control are demanding real-time or super-real-time simulation.To solve the above issues, this thesis mainly studies the simulation algorithm for electromagnetic transient process, its implementation with parallel computing, and the design of corresponding components. The mathematical model of power systems, the optimal power network partition scheme, electromagnetic transient simulation on single computer and for parallel computing, transient stability analysis are discussed. The computer program for single computer and components for parallel computing are implemented.Test cases are used to verify the results. The testing results with single computer and parallel computing components show that the errors are within a permissible range when the algorithm designed in this thesis is used to perform electromechanical transient simulation, verifying the functionality of the transient stability analysis. The performance of the two proposed algorithms in this thesis is compared, and it shows that the component program for parallel computing performs the simulation much faster than that for single computer computing. Therefore, it has the potential to be used in future.
