Internet-based platform for power system simulating and planning

Power system simulation and plan are considered as essential tools for design, operation and control of power systems. The existing software for power system simulating and planning is essentially desktop application, which limits its application power. Due to the worldwide expansion of interest in Internet in the past few years, an Internet-based application development has appeared in some technical fields. A great progress on the Internet technique makes it easy to implement the Web-based system. In this paper a process is described for implementing the Internet-based simulation and plan platform of power systems. The platform supports some necessary calculation or analysis methods of the power system simulation and plan, such as load flow calculation, short circuit calculation, harmonic analysis, load forecasting, plan optimization of electric networks, and economic analysis. The cookies in the client-side and the session state objects in server-side are used for data exchanging between Web pages. Both XML documents and databases are supported for interchanging input data and results between Web servers and clients. The structure of XML and the way to construct the Web services are discussed. The development environment of the platform is analyzed.
