摘要
Abstract
To avoid the dynamic problems caused by dynamic and static loads in the operation of a power electronic power system,which affect the system stability,a modeling and analysis method for the voltage power angle dynamic stability is proposed.The continuation method is used to track the equilibrium solution manifold of the power system,and the small disturbance analysis method is used to calculate the voltage power angle state matrix to judge the dynamic stability of voltage power angle.By means of the power system stability mode discrimination method,the correlation between voltage and power angle state variables in the instability state is analyzed,the system instability category is determined,and the construction and analysis of voltage and power angle dynamic stability model is realized.Experimental results show that the load model is directly related to the category of dynamic instability of power system in an electronic environment.The static load model is easy to cause power angle instability,while the dynamic load model is easy to cause voltage instability.The time-domain simulation results are consistent with the discrimination results of state variable participation factor.Through the tests of power angle instability and voltage instability,the generator angle and node voltage are analyzed.It is proved that the proposed method has a good effect in the analysis of voltage and power angle dynamic stability,providing certain reference value for researches in the field of power system engineering.关键词
