Research And Implementation Of Performance Testing System Of Power Distribution Broadband Wireless Network Based On Business

Along with the intelligentialize development of power distribution network, the application system of power distribution network is becoming more and more. Each application system has different information Acquisition point and controlled point, resulting in the exponential growth of access point in the communication system. Although has high reliability, traditional communication network using fibre-optical or wire cable has obvious defects in deploy and cost. With the characteristics of Flexible access, high security, high business support ability and lower cost of investments, it is a technology trends to use broadband wireless network in distribution automation and electricity information acqurrsition.One Can foresee that broadband wireless communication technology will be more and more used in distribution network, but the study of performance testing of distribution broadband wireless network is deficient. Especially, almost none of performance testing method or standard of distribution wireless network is based on business. It is necessary to make the performance testing plan and testing environment of distribution broadband wireless network based on actual business.The thesis focuses on the study of performance testing scheme of power distribution broadband wireless network based on business. On the basis of analysis of the power distribution communication networks, the requirement analysis and scheme design of the performance testing system of power distribution broadband wireless network based on business are made. The key technologies of the testing system is clear cut and detailed studied. Adopting the modular thought, the software structure of the testing system based on business is designed. On the analysis of distribution communication business, the traffic models are built and the testing traffic is generated with the traffic models.Based on the simulation of the protocol of IEC60870-5-104used in distribution automation and Q/GDW373-2009used in electricity information acquirsition, the testing system is designed. The main functions of them are testing packet encapsulating, the protocol flow simulation, and the packet sending and receiving. On the packet sending and reveiving process, the performance is statisticed.Finally, the performance testing software is deployed. In the Environment of typical business and the maximum flow, the system performance is tested. The test resules show that the broadband wireless network can support the general distribution communication service.
