摘　　要：研究配变重过载下的配网运营动态监控平台实时任务容错调度算法,以解决配网运营动态监控平台执行配变重过载监控任务时可调度性差的问题。依据分层调度思想,将实时任务容错调度划分为上层调度算法和下层调度算法,通过上层调度算法利用Logistic模型预测是否存在配变重过载情况,存在配变重过载情况时,进入下层调度算法。下层调度算法利用平台的优先级属性列表,建立平台管理机执行配变重过载动态监控任务时的有效传递函数,利用码元调制方法获取平台任务调度输出,保障配网运营动态监控平台稳定执行配变重过载动态监控任务。实例分析结果表明,配网运营动态监控同时执行30个配变重过载动态监控任务时,其容错调度成功率高于93%,验证该算法具有良好的实时任务容错调度有效性。This paper studied the real-time task fault-tolerant scheduling algorithm of the distribution network dynamic monitoring platform with heavy-overload distribution transformer in order to solve the problem of poor schedulability of distribution network dynamic monitoring platform when performing heavy overload monitoring task of distribution transformer.According to the layered scheduling idea,fault-tolerant scheduling of real-time tasks were classified into upper scheduling algorithm and lower scheduling algorithm.Through the upper scheduling algorithm,the logistic model was used to predict whether there existed heavy-overload distribution transformer,and transfered to lower scheduling algorithm when encountering heavy overload.The lower scheduling algorithm used the priority attribute list of the platform to establish effective transfer function when platform manager performs dynamic monitoring task,and adopted symbol modulation method to obtain scheduling output of the platform task,so as to ensure stable implementation of dynamic monitoring distribution transformer overload.The proposed algorithm was proved by case analysis to achieve a success rate of fault-tolerant scheduling higher than 93%when coping with simultaneous 30 dynamic monitoring tasks of heavy-overload distribution network operation,and satisfactorily effective in real-time task fault-tolerant scheduling.
