基于N-1原则的输电断面热稳定功率极限评估
Evaluation on Thermal Stability Power Limit of Transmission Section Based on N-1 Principle
摘要
Abstract
To improve the operation safety level of power system,an evaluation method on thermal stability power limit of transmission section based on N-1 principle is put forward. The control parameters of generator nodes on line power are obtained by computing the power sensitivity matrix. By taking the lines on the transmission section as target lines suc⁃cessively,and on the basis of satisfying constraints such as line redundancy,power increase due to broken line,and ad⁃justable generator capacity,the generator output is adjusted,and the maximum transmission section powers correspond⁃ing to the target lines are obtained using optimization method,of which the minimum value is taken as the thermal stabili⁃ty power limit of the transmission section. The correctness of the proposed method is verified in IEEE 39-node system.关键词
