摘　　要：为提升各级调控系统全网统一在线分析计算能力,提出了一种面向统一计算分析的互联大电网一体化节点支路计算模型服务方法,并研发相关软件。该服务主要包括模型校验、分布式拓扑分析、数据交互及一体化节点支路计算模型生成功能。利用该软件,各级调控中心可按需实时获取全网节点支路计算模型,实现全网模型数据的实时共享,进而在线分析应用可利用"全网节点支路计算模型+本地物理模型"实现全网统一分析计算,有效提高其计算结果精度和完整性。在实验室仿真环境的测试结果验证了所提方法的可行性和有效性,提升了多级调度数据模型共享效率。In order to improve whole power grid unified online analysis and computing capability for all levels of dispatching and control systems, the paper presented an integrated node-branch computing model service of large power grid for unified analysis, and related soft-ware was researched and developed in smart grid dispatching and control systems. Main functions of the service were model validation, distributed topology analysis, data exchange and integrated node-branch computing model generation. Taking advantage of this software, all levels of dispatching and control center could get whole power grid node-branch computing model in real time upon demand, sharing whole power grid model and data in real time. Online analysis applications could take advantage of ＇whole power grid node-branch computing model ＋ local power grid physical model＇ to realize whole power grid unified analysis and computation, effectively improving accuracy and integrity of results. Simulation was carried out in laboratory environment and feasibility and practicality of the proposed method was verified. The presented method improves data and model sharing efficiency in multi-level dispatching systems.
