Current situation of large-scale power grid simulation tools and their popularization and application in North China Power Grid
Conventional electromechanical transient simulation tools are not good enough in analyzing the problems of voltage instability of DC sending-/receiving-end caused by AC/DC faults,wide-frequency oscillation caused by the interaction between multiple voltage source converters and AC power grid,and so on. It is difficult to accurately simulate the action of DC system by conventional electromechanical transient simulation tools,which affects the formulation of control measures for actual power grid operation. Therefore,the current situation of simulation tools for large-scale AC/DC hybrid power grid is investigated,and the popularization and application ideas in North China Power Grid are put forward. Firstly,the mature and feasible simulation technologies for large-scale AC/DC hybrid power grid are briefly introduced. Then,the current situations of domestic large-scale AC/DC power grid simulation tools in terms of model development,parameter maintenance and users’ unfriendly experience are mainly analyzed. The achievements in the independent research and development of core technologies and the shortcomings in the popularization and application of the electromechanical-electromagnetic hybrid simulation,digital and analog mixed simulation and full electromagnetic simulation tools are highlighted. Finally,according to the production demand of North China Power Grid,the current positioning of various simulation tools in North China Power Grid is clarified and the following working ideas are put forward. The work can also be used for reference by other dispatching and production organizations,which can improve the control ability of large-scale AC/DC hybrid power grid and indirectly improve the practical level of simulation tools.
