【摘要】：目前,電力系統(tǒng)的一個重要的研究方向是智能電網(wǎng),它具有強大的工程背景和應用,具有巨大的市場潛力和發(fā)展趨勢。智能電網(wǎng)的智能調度網(wǎng)絡在國內和國外都是非常火熱的關鍵技術,當前的研究熱點著眼于研究智能編程和調度,包括電力分配網(wǎng)絡處于正常操作狀態(tài),故障,過載下三個條件分析處理和調度的策略。在智能調度網(wǎng)絡中,網(wǎng)絡分析、信息處理和分發(fā)在被分配到該地區(qū)的每個節(jié)點,并與智能調度網(wǎng)絡的拓撲結構和網(wǎng)絡結構的最佳模式判斷隔離算法誤差是否正常運作,有助于智能電網(wǎng)的快速功能實現(xiàn)。為了保證網(wǎng)絡的安全性和經(jīng)濟穩(wěn)定,并在發(fā)生錯誤時針對特定區(qū)域電力網(wǎng)絡的快速調度和高效運行,需要快速、準確地定位故障,并在該地區(qū)快速進行故障隔離,以達到將事故控制在最少的影響區(qū)域內。這說明了網(wǎng)絡模型結構的變化將影響實際的運作,電氣設備之間的布線,以及后面的建模節(jié)點的數(shù)目和網(wǎng)絡分布,優(yōu)化數(shù)據(jù)結構,并對所有這些操作簡化計算,以及減少對計算機的內存需求,為改善該地區(qū)的故障隔離和實際應用提供了有力的保障。智能調度網(wǎng)絡,在過載的情況下,無論是安全性和穩(wěn)定性,應該是部分地區(qū)一直缺乏電量。為了實現(xiàn)網(wǎng)絡優(yōu)化的好處,需要提供計算區(qū)域能源優(yōu)先的算法,同時考慮經(jīng)濟和政治因素,挖掘排名算法并進行區(qū)域標準化。當電力存在一個多小時的赤字,只需運行該提案中的排名算法進行電網(wǎng)轄區(qū)用電單位的重新調度。通過優(yōu)先級和額定負載,以確保智能調度網(wǎng)絡在過載的情況下,也能保證電網(wǎng)的安全性和穩(wěn)定性,最終提高了經(jīng)濟收益和調度效率�；谘芯亢驼{度系統(tǒng)的開發(fā)在實際應用中靈武水電公司得到非常好的測試結果,并且減少了整體的停電時間,提高最終的經(jīng)濟效益。
[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.
