瞬时功率计算方法的深度研究与应用
Study and Application of Instantaneous Power Calculation Method
摘要
Abstract
To systematically explore and accurately calculate the components of instantaneous power,an instantaneous power calculation method with and without the consideration of zero-sequence component are given based on the rota?tional coordinate system under an asymmetrical working condition. The three-phase instantaneous power calculation method and single-phase power calculation method are compared and analyzed,and a method to solve the expected val?ue of reactive power exchange in an high-voltage direct current(HVDC)system with dynamic adaptability is proposed. Finally,based on PSCAD/EMTDC simulation,the accuracy of the analytical calculation formula is verified;moreover, the proposed method can effectively control the reactive power exchange of the system to improve its fault recovery per?formance.关键词
