Steady-state Stability Analysis of Wind-thermal Bundled Sending System
摘要
Abstract
The steady-state stability and the features of stability limit on a wind-thermal bundled sending system are studied.A variable speed wind turbine with power electronic interface can control the power quickly and flexibly.In the steady-state stability analysis,by neglecting the fast dynamics of wind power regulation,the wind power is simplified to a static power inj ection model,and can be described as an algebraic equation in the system dynamic process.By proposing a triangular transformation model of the wind-thermal bundled transmission system,the change of steady-state stability limits on thermal generator and the sending interface with wind power is investigated.In the wind-thermal bundled transmission system,when wind power increases from zero,the steady-state stability limit on thermal generator decreases,and the limit on the sending interface first increases,then decreases.Simulation results in the test system and an actual system have validated the conclusion.关键词
