Research On Analysis And Assessment Of Black-Start Schemes And Reconstruction Of System Topology

The restoration of power system after a complete blackout is a very important problem. How to choose the schemes of black-start can help dispatchers to establish black-start schemes and restore power system as soon as possible. Firstly , the factor of the generator units is discussed about establishing black-start schemes. And combining with DEAHP, how to evaluate power system black-start schemes in the Southern Hebei Power System is investigated in this thesis. And building a Data Envelopment Analysis (DEA) model to evaluate a group of schemes , an automatic assessment system of black-start schemes is developed and integrated into a decision support system for black-start. The system developed in the thesis can evaluate a group of schemes. Making use of DEA and database based on expert experience, the system can assess these schemes and get the relatively validity so that scientific and instructive decision reference can be provided to the dispatchers. At last reconstruction of system topology is researched...
