【摘要】：目前,电力系统的一个重要的研究方向是智能电网,它具有强大的工程背景和应用,具有巨大的市场潜力和发展趋势。智能电网的智能调度网络在国内和国外都是非常火热的关键技术,当前的研究热点着眼于研究智能编程和调度,包括电力分配网络处于正常操作状态,故障,过载下三个条件分析处理和调度的策略。在智能调度网络中,网络分析、信息处理和分发在被分配到该地区的每个节点,并与智能调度网络的拓扑结构和网络结构的最佳模式判断隔离算法误差是否正常运作,有助于智能电网的快速功能实现。为了保证网络的安全性和经济稳定,并在发生错误时针对特定区域电力网络的快速调度和高效运行,需要快速、准确地定位故障,并在该地区快速进行故障隔离,以达到将事故控制在最少的影响区域内。这说明了网络模型结构的变化将影响实际的运作,电气设备之间的布线,以及后面的建模节点的数目和网络分布,优化数据结构,并对所有这些操作简化计算,以及减少对计算机的内存需求,为改善该地区的故障隔离和实际应用提供了有力的保障。智能调度网络,在过载的情况下,无论是安全性和稳定性,应该是部分地区一直缺乏电量。为了实现网络优化的好处,需要提供计算区域能源优先的算法,同时考虑经济和政治因素,挖掘排名算法并进行区域标准化。当电力存在一个多小时的赤字,只需运行该提案中的排名算法进行电网辖区用电单位的重新调度。通过优先级和额定负载,以确保智能调度网络在过载的情况下,也能保证电网的安全性和稳定性,最终提高了经济收益和调度效率。基于研究和调度系统的开发在实际应用中灵武水电公司得到非常好的测试结果,并且减少了整体的停电时间,提高最终的经济效益。
[Abstract]:At present, smart grid is an important research direction of power system, which has strong engineering background and application. Intelligent dispatching network of smart grid is a very hot key technology both at home and abroad. The current research focus is on intelligent programming and scheduling. Including the power distribution network in the normal operation, failure, overload under three conditional analysis and scheduling strategy. In intelligent dispatching network, network analysis. The information is processed and distributed at each node assigned to the area, and the optimal pattern of the topology and network structure of the intelligent scheduling network determines whether the isolation algorithm error is functioning properly. In order to ensure the security and economic stability of the network and the rapid dispatch and efficient operation of the power network in a specific area when errors occur, it is necessary to quickly. The fault is located accurately, and fault isolation is carried out quickly in this area, so that the accident can be controlled in the least affected area, which shows that the change of the network model structure will affect the actual operation. Wiring between electrical devices, and the number and network distribution of subsequent modeling nodes, optimizing data structures, simplifying calculations for all these operations, and reducing the memory requirements for computers. In order to improve the fault isolation and practical application in this area, it provides a strong guarantee. Intelligent scheduling network, in the case of overload, whether it is security and stability. In order to realize the benefits of network optimization, it is necessary to provide an algorithm to calculate regional energy priority, taking into account economic and political factors. Mining the ranking algorithm and standardizing the region. When the power has a deficit of more than an hour, simply run the ranking algorithm in the proposal for the rescheduling of electricity units in the power grid area. Through priority and rated load. In order to ensure the intelligent dispatching network in the case of overload, but also to ensure the security and stability of the grid. Finally, the economic benefits and scheduling efficiency are improved. Based on the research and scheduling system development in the practical application of Lingwu Hydropower Company to obtain very good test results, and reduce the overall blackout time. Improve the ultimate economic benefits.
