摘要
针对电力系统发生大扰动后发电机功角轨线变化与距离故障点远近有关的特点,将交互式多模型(IMM)自适应跟踪算法成功地用于预测电力系统暂态稳定性。该自适应IMM算法采用机动目标"当前"统计模型、常加速度模型和常速度模型交互作用构成。文中详细描述了自适应IMM算法的实现步骤,并应用于发电机功角跟踪预测过程中,通过仿真结果验证了所提算法的实用性。
Power angle trajectory is related to the faulted position.According to the characteristic, a new interacting multiple model (IMM) adaptive tracking algorithm to predict transient stability is presented. In this algorithm, 'current' statistical model, constant acceleration model and constant velocity model are running in parallel, the angle trajectory prediction is the result of interaction of these models. Detailed description of the IMM algorithm is also given. The effectiveness of the proposed algorithm is shown by simulation results.
