摘　　要：当前的技术降损平台虽然在理论线损计算、无功优化和潮流调度优化等方面取得了一定成果,但对供电方的无功补偿能力缺乏有效感知,对用电方的无功补偿意愿缺乏精准引导。针对上述问题,提出了考虑供用电双方无功补偿潜力的省级技术降损互动管控平台建设方案,并提出了“低压无功补偿设备运行状态诊断”和“专变用户无功潜力挖掘”两个技术降损高级功能的设计与实施方案。前者可有效提高低压无功补偿设备的有效利用率、充分挖掘低压配电网的网损管理潜力。后者通过平台的信息共享与互动机制形成了协同治理、互利共赢的无功降损体系。目前,所提平台已在某省电网投入实际应用。前者功能的验证准确率达到了93.33%;后者功能共梳理出707户目标用户,并在平台机制的引导下逐步开展治理。Although the current technology loss reduction platform has achieved certain results in theoretical line loss calculation,reactive power and power flow scheduling optimization,it lacks effective perception of the reactive power compensation capability of the power supplier.It also lacks accurate guidance on the reactive power compensation willingness of the power consumer.In view of these problems,this paper puts forward a construction scheme of provincial technical loss reduction interactive management and control platform considering the potential of reactive power compensation of both power supply and demand sides.It also puts forward the design and implementation scheme of two technical loss reduction advanced functions of"operational state diagnosis of low voltage reactive power compensation equipment"and"special transformer user reactive power potential mining".The former can effectively improve the effective utilization rate of low-voltage reactive power compensation equipment and fully tap the network loss management potential of a low-voltage distribution network.The latter forms a collaborative governance,and a mutually beneficial and win-win reactive power loss reduction system through the information sharing and interaction mechanism of the platform.At present,the platform proposed in this paper has been put into practical application in a provincial power grid.The verification accuracy of the former function mentioned above is 93.33%.The latter has sorted out a total of 707 target users and gradually carried out treatment under the guidance of the platform mechanism.
