面向电网运行方式计算分析的BPA数据分布式管理平台

BPA由于其天然分布特征和其数据以文件形式存储,无法支持分布式的应用场景;另外,原先的数据卡填写操作繁琐,容易出错。针对上述问题研发了BPA数据分布式管理平台,平台采用客户端-服务器(client/server,C/S)和浏览器-服务器(browser/server,B/S)混合结构及Java2 Enterprise Edition(J2EE)技术,应用内存数据库作为功能支撑,商务数据库作为B/S数据支撑,实现通过网络方式进行数据传送和处理;由此搭建了一个以BPA数据管理操作和生成计算文件作为核心的公共数据工作平台。平台可以根据电网实际情况自动进行电网模型拼接,方便网、省、地调数据的各自管理和维护;采用关联策略为平台的BPA数据操作提供了便捷的模型参数编缉操作,避免了操作人员对关联模型的遗漏而造成计算文件中模型不完整而使得计算不成功;为电网运行计算分析人员提供了辅助平台。

Distributed Management Platform for BPA Data Oriented Calculation and Analysis on Power Grid Operation Mode

For reasons of natural distribution characteristics of BPA and document storage form of its data, it is not able to support distributed application scenarios. In addition, it is easy to make mistakes for reason of tedious filling operation for o- riginal data card. Aiming at above problems, this paper develops distributed management platform for BPA data which uses composite structure of client/server and browser/server and Java2 Enterprise Edition technology, applies memory database as function support and business database as B/S data support to realize data transmission and disposal by means of network. Meanwhile, it establishes a public data working platform which regards BPA data management operation and producing cal- culating document as core. This working platform is able to realize power grid model merging according to grid reality which is convenient to realize self management and maintenance for data of grid, province and regional dispatching center. By u- sing correlation strategy, it is able to provide convenient and fast editing operation on model parameters for BPA data opera- tion, avoid unsuccessful calculation caused for reason of operational personnel omitting correlation model which may result in incomplete model in calculation document. In addition, this platform is useful to provide an assistant platform for power grid operation calculation and analysis personnel.
