随着地县一体化建设的推进，以适应新形势、简化管理、进一步提高地区电网电压无功自动控制效率为目的，提出了分布式电压无功自动控制系统。系统根据电网监控权，以变电站为基本单元，将全模型划分为多个属于不同的监控区域和县区局的本地模型。采用分布式技术，将服务部署于物理上分散的多个节点机，以本地模型为单元分配给节点机，进行监视、计算和控制。软隔离消息总线，保证相关人员在所属的模型视图内进行电网监视和模型维护，透明化底层信息。与原有的集中式控制相比，系统体系结构更加灵活，便于扩展，可靠性更高，计算和控制效率得到了明显提升，满足地县一体化的建设要求。%With the advance of municipal-county integration, in order to simplify management and further improve the efficiency of automatic control, a distributed voltage and reactive power automatic control system is adopted. Based on the monitor right, taking substation as the basic unit, the system divides the whole model into several local models belonging to different monitoring area;using a distributed technology, services are deployed on multiple physically distributed node computers, assigning the local model to the node computer to monitor, calculate and control;soft isolation message bus ensures that the relevant personnel monitor the power grid and maintain the model in their view of the model, transparenting the underlying information. Compared to the original centralized control, system has more flexible architecture, scalable, and higher reliability. Its calculation and control efficiency is improved significantly. It meets the requirements of municipal-county integration.
