考虑设备健康状态的智能调度策略

Intelligent dispatching strategy considering the health condition of power equipments

智能电网的发展对设备的使用效率提出了更高的要求,结合状态检修结果以及传统故障率的推算,提出了设备健康负荷指数的新指标。该指标能够同时反应出设备的健康状态和设备的负载率情况,实现均衡设备健康状态与负荷情况的目标。结合该指标,又进一步对调度策略研究。通过一条手拉手线路算例验证了该指标可以实现变压器负载率能够随着变压器健康状态的变化而做合适的调整,再综合考虑线损率等传统的经济运行指标,实现运行方式优化的目的,对未来的智能调度有一定指导意义。

In order to meet the requirements of utilization of the equipments with the development of smart grid, a new index named health-load index （HLI） is presented. Such index is based on the result of condition-based maintenance and traditional failure rate calculation. It can reflect both the asset health condition and asset utilization and thus can balance them. Moreover, based on such index, a dispatching strategy is presented and tested by a case of hand-in-hand connecting method. The test validates the idea of adaption between the health condition and the utilization of the transformers. Then a better network reconflguration can be reached with the consideration of power loss which is a traditional index of economic dispatching. It has great meaning to the future intelligent dispatching.
