中文摘要： 由于智能电网对通信网络的可靠性具有特殊要求，目前现有的无线通信网络并不适用于智能电网。在本项目中我们将结合云南地区建设智能电网的区域特点，采用目前最新适用于工业领域的保障严格实时的WirelessHART无线传感器网络技术，对面向云南智能电网的工业级严格实时无线传感网络关键技术进行研究。我们首先通过对电网内异构业务采用分粒度的基于业务的低复杂度的优化调度算法，并扩展到复杂拓扑网络结构应用中；然后考虑无线链路存在的非对称问题对智能电网实时性能影响，提出针对智能电网的无线链路优化调度算法。基于这两方面的研究，我们拟对基于先验优化的组网可行性进行研究，并期望得到在电网用户最小需求保障下进行无线传感器网络部署的理论参考参数取值。此外，我们拟提出一种新的结合智能电网中一次系统可靠性、控制保护系统节点的可靠性、通信的可达性以及通信时延约束综合的可靠性模型研究，实现对智能电网的可靠性性能进行评估。

英文摘要： Due to the special requirement for the communication systems on Smart grid, the existing wireless networks do not fit for the applications in the smart grid. In this project, we plan to adopt the WirelessHART based industrial wireless sensor networks, which is considered as the most promising technology for the rigorous delay applications in industrial side. Considering the district features for the smart grid in Yunnan province, our research will focus on the key technologies of the industrial rigorous real-time wireless sensor networks for the smart grid in Yunnan. We first study on the low complexity scheduling algorithm for the heterogenous traffics in complex network topology environment by using superperiod and slot based method.Then we study on the wireless link scheduling under smart grid considering the asymmetric link problem, which is neglected by many research works. Combining with these above two research works, we expect to get predictive networks parameters during the deployment, which should satisfy the minimum rewards from the users. Moreover, we will propose a new model for evaluating the reliability performance for the smart grid, which is the first time to consider about the reliability of the primary systems, reliability of nodes of control and protection system, the success of communication and the deadline constraints.
