The Research On Server Mode For Analysis Platform Of Transmission And Distribution Network

The analysis Platform of transmission and distribution network can analyse and simulate transmission and distribution network system, overcome hidden accident, which is important method to improve transmission and distribution power grid management lever. the transmission and distribution power grid analysis software,in the past, exised some disadvantages,for example,worse openess,single function,difficult extension and maintenance.So exploiting the transmission and distribution power grid service platform which is universality,interactive,distributed has important theorectical significance and interactive value.The IEC 61970-301(CIM) standard was established to solve the different power system model. Firstly,the paper analysises the Common Information Model (CIM),and summarizes the modeling method using CIM and how to expand CIM according to the practical application.On this basis,the mapping between object module and relational database is proposed,and established CIM model in the Relation Database SQL Server 2000 and the Real-time Database. Secondly, the power grid topology analysis, which adoptes the definition method of power grid topology referenced in CIM, is researched. And the paper finishes the power grid's static topology.dynamic topology analysis and the local topology analysis when the position of breakers changes, and takes the example to verify correctness and feasibioity of the method. Finally, the data exchange interface is designed according to IEC 61970-CIS standard.Based on the established model and method in Visual C++ 2005, the prototype service system is established, and the relevant client test program of the system is compiled. The later completes the inserving, deleting, searching and updating operation of Real-time Database in server end. The original data about load flow calculations will be generated in server end when load flow calculations are requested in client end. The testing result demonstrates the reasonableness and correctness of server system design.
