实用化分布式动态潮流计算系统的设计与实现

分布式动态潮流可以很好地解决电网规模过大和数据广域分布的一体化潮流计算问题。从实用化角度出发,结合公共对象请求代理结构(CORBA)技术优势,设计并实现了一种基于CORBA和异步迭代模式的分布式动态潮流实用化计算系统,解决了实际电网在边界存在较大重叠区域时的分布式计算一体化建模问题。通过引入注册、激活、启动的分布式管理机制,解决了多子系统同时发起计算时的冲突消解等关键问题。在搭建的模拟广域网测试平台上,以IEEE 118节点系统为例,对该系统的快速性、鲁棒性和异步迭代效果等进行了测试;以深圳地调电网为例,通过与OPEN-3000能量管理系统(EMS)接口,完成了实用化测试。测试结果证明了所设计系统的实用性和异步迭代潮流算法的有效性。

Design and Implementation of a Practical Distributed Power Flow Calculation System

Distributed dynamic power flow can well solve the integrated power flow calculation problems of a power system with excessively large scale and wide area distributed data.Proceeding from the practical need and with common object request breaker architecture(CORBA) technologies,a distributed power flow calculation system based on CORBA and asynchronous iterative techniques is designed and implemented,to solve the integrated modeling problems of distributed computation with large overlapping areas on the edge of the real networks.The conflict resolution problems caused by multi-subsystem simultaneously starting calculation are solved by employing managing mechanisms such as registering,activating,starting,etc.On the makeshift test platform of the analog wide area network,the speed,robustness and effectiveness of asynchronous iteration are tested in the IEEE 118-node power system.By interfacing with the Open3000 energy management system(EMS),further practical tests are performed in Shenzhen power grid.The test results verify the applicability and the effectiveness of asynchronous iteration of the proposed system.
