针对现有电网模型中心建设模式中存在系统异构、模型交互效率低、交互过程自动化水平不高等问题,文中提出一种基于厂站粒度的电网模型中心构建方法。通过研究基于厂站粒度的电网模型交互技术和按需模型代理服务机制,解决调度系统间模型中心建设中存在的模型融合、交互效率、安全性,以及模型分区维护方面存在的问题。文中通过实际电网系统的案例,验证了以厂站为粒度的电网模型中心构建方法能够对模型中心建设中的模型交互效率、模型质量、自动化维护水平等方面进行改善和提高,解决异构调度系统接入模型中心存在的问题。

In view of the problems of system heterogeneity, low efficiency in model interaction, low automation level of interactive process existing in the construction mode of power grid model center, a construction method for power grid model center is put forward based on the particle size of power plant/substation. Through a study of power grid model interaction technology and on-demand model proxy service mechanism with the particle size of power plant/substation, the model fusion, interaction efficiency, security and the model partition maintenance problems are solved in the construction of model center between dispatching systems. With an actual power grid as an example, it is verified that the proposed construction method is capable of improving the interaction efficiency, model quality, and automation maintenance level in the building of model center, as well as solving the problems of the heterogeneous scheduling system to be integrated into the model center.
