一体化电能量计量主站系统关键技术研究

Key Techniques of Integrated Master Station for Tele-meter Reading System

随着电网信息化建设的不断发展和应电网运行智能化的要求,电力系统二次一体化的重要性日益明显。在调度主站系统中,能量管理系统(energy management system,EMS)和电能量计量系统(tele-meter reading system,TMR)通常是两套独立运行的系统。为实现横向专业融合,主要讨论这两套系统的一体化技术方案,提出基于IEC 61970标准的一体化电能量计量系统,阐述具体实施的关键技术,分析一体化运行的优点,为电网二次系统运行的智能化水平提高打下坚实基础。

With the development of informatization construction of power grid and the requirements of intelligent grid operation, the importance of the secondary power system integration has become increasingly evident. In the systems of dispatch center, the energy management system (EMS) and tele-meter reading (TMR) system are usually two separate systems. In order to achieve horizontal integration expertise, the integration of the two systems is discussed and an integrated electric energy metering system which based on the IEC 61970 standard is proposed; the specific implementation of the key technologies is elaborated and the advantages of an integrated operation are analyzed. It lays a solid foundation for the development of the intelligent level of the secondary system of power grid.
