Key technology of scalable SCADA system for microgrids

为了突破传统的微电网SCADA系统结构封闭、难以满足二次开发需求的局限性,提出可扩展的微电网SCADA系统模型,满足多种新能源元件的监测和计算需要,快速工程化,同时支持多种微网运行控制策略及扩展.系统基于面向服务架构(SOA)进行业务功能的封装与扩展,实现一体化模型维护方案,并且提供面向设备与模型的智能化计算与控制方法.针对传统微电网SCADA业务功能,应用基于SOA技术的重构,建立具备良好适应性与多重扩展性的微电网SCADA平台,提升SCADA技术的互联性、灵活性与多样性,应用于不同形态的微电网.通过南都储能电站案例,展现系统开放互联的应用效果.

A scalable SCADA system model was built in order to break through the limitations of traditional SCADA system for microgrids including the closed system structure and the lack of continuous development.The scalable SCADA system which meets the monitoring and calculation needs of various new energy components, can be promoted rapidlys and provide support for application and extension of multiple operation control strategies for microgrids. Based on service-oriented architecture（SOA）, the encapsulation and extension of the modularized functions were realized. The integrated modeling maintenance scheme was proposed, and the equipment-oriented and model-oriented intelligent calculation and control methods were provided. Through reconfiguration of the traditional SCADA services based on SOA technology, a SCADA platform with strong adaptability and multi-dimensional extensibility for microgrids was set up.The connectivity, flexibility, and diversity of SCADA technologies were promoted so that the system can be used in different forms of microgrids. The application effects of the interconnection and extension of the system were demonstrated by the engineering project of Nandu energy-storage power station.
