摘　　要：风火打捆系统特点是大功率远距离外送,出现大扰动后失稳风险较高,因此风火打捆系统暂态稳定控制是一个亟需研究的课题。基于等面积法则提出直流功率与切机相结合的风火打捆系统暂态稳定控制策略。通过量测数据可以预判风火打捆系统的暂态稳定性并给出控制策略,该方法简单可靠,计算速度快,可以应用到在线运算,具有较大的工程应用价值。Wind-thermal-bundled system has characteristics of high power and distance transmission, the system is easily unstable after large disturbance. Therefore, control strategy for transient stability of wind-thermal-bundled system is a significant research. The control strategy for transient stability of wind-thermal-bundled system in which the DC power combines with generator tripping is proposed, which is based on equal area criterion. Transient stability of wind-thermal-bundled system can be estimated by measurement data, and then control strategy can be proposed. This method is simple, reliable and has fast computing speed, which can be applied to online calculation. This paper has great engineering value.
