在對張掖市農村電網改造和農電負荷變化情況調查的基礎上，基于柔性輸電理論，為提高農網供電質量和供電可靠性，分析了在張掖市農網中適時采用FTU技術的必要性及可行性。采用FTU技術建立配電設備與饋線主站之間的通信，獲取配電系統運行控制及管理所需數據，執(zhí)行主站給出的對配電設備的控制調節(jié)指令，實現提高供電質量和供電可靠性，降低電能損耗，提高設備利用率，減少維護費用，節(jié)省總投資的效果。實現正常情況下的優(yōu)化配網運行和故障時的自動判別和自動隔離故障區(qū)以及恢復非故障區(qū)供電。為今后張掖市農網的進一步改造提出決策依據。

　　Abstract:

　　Based on the investigation of the rural power grids and rural power load changes of Zhangye city， using FACTS as the theory guide， in order to improve the quality and reliability of rural power supply， this paper analyzed the necessity and feasibility of timely using FTU technology in the rural network of Zhangye city. Communication between distribution equipment and master feeder was established to obtain the control and management data of the system， and to implement the master control instruction to distribution equipment， which improved power quality and supply reliability， reduced the power loss， also improved equipment utilization， reduced maintenance costs and saved total investment. Using of FTU technology optimized operation of distribution network under normal circumstances， realized automatic identification of fault and isolating fault area automatically， it also recovered the non-fault zone supply， which provides decision basis for the future transformation of rural power network in Zhangye city.
