基于CIM的稀疏矩阵模型设计

DESIGN OF A CIM-BASED SPARSE MATRIX MODEL

基于公共信息模型(CIM)建立了一个通用于电力系统应用程序的稀疏矩阵模型。利用面向对象技术将稀疏矩阵及其运算封装为一个符合CIM数据模型标准的、可被各种应用程序调用和共享的通用数据对象。为了保证矩阵运算的效率和数值稳定性,针对各类应用程序进行了特定的优化设计。提出的矩阵模型实现了数据与算法的解耦,从而大大提高了应用程序的可维护性和可扩展性。基于CIM的标准框架有助于各种应用程序以及各级系统间的集成和信息交互,体现了即插即用的组件软件系统的思想。

A CIM-based generic sparse matrix model for various power system analysis applications is presented. By using object-oriented methodology, sparse matrix operations are encapsulated as a common program interface and can be utilized and interchanged by power system applications just as other data models of CIM. The design of specific algorithm optimization for different power system application modules guarantees numerical stability and efficient sparsity implementation. The sparse matrix model proposed reduces the coupling of data and algorithm while enhancing the maintainability and extensibility. Its CIM-based framework helps interfacing power system analysis applications with other applications or systems, reflecting a development toward a truly 'plug and play' format software.
