摘要
首先分析了目前传统电力软件系统中存在的缺陷与问题,如基础计算功能重复开发,不利于升级与维护,软件开发较复杂。其次分析了组件技术在解决这些问题上的独到之处,并提出采用组件技术来实现电力系统基础计算软件。接着介绍了基于J2EE的软件开发方法和软件开发的具体过程,说明了J2EE体系结构是适合于电力系统软件开发的方案。并利用J2EE的EJB技术实现了一个通用的潮流计算软件。该软件采用了许多稀疏技术,如稀疏导纳矩阵的存储和稀疏矩阵的因子表分解等。最后以IEEE系统14节点网络为例对软件进行了测试,收敛性和计算速度均达到要求,与BPA相比,误差在允许范围内,通过实例验证了软件的独立性、正确性和对电力系统应用软件体系结构改进的可行性。
The shortcomings of power system software are of the traditional architecture discussed, such as the repeated development of the computing module, the difficulties in the upgrade and development of software. The unique advantage of the component technique in solving the above problems is analyzed, and a thought of applying the technique to the development of software is suggested. The method and process of developing software by J2EE architecture are introduced. It is proved that the J2EE architecture is the best settlement for power system software. The universal power flow calculation module is designed and implemented, in which sparseness technique is adopted, such as the storage of the sparse matrix and the decomposing of the factorial table. The software is tested by an example in IEEE system. It shows that the computing speed fulfills the demand and the error is within the acceptant range compared with BPA. The effectiveness of the software is proved through case study.
