“…The low voltage problem of rural power grid has also become an important issue that restricts the construction of rural power grids and affects the quality of life of villagers. At present, the low voltage problem of rural power grid can be optimized by substation, line, and distribution voltage three-level joint adjustment technology [1], and there are better solutions to the problem, and it can also be installed by coupling capacitor reactive compensation equipment [2], Optimize the rural network structure [3], add new distribution transformers or increase capacity [4], configure distribution transformers with on-load voltage regulation function [5] and other means. Most of the research is concentrated in the qualitative analysis stage.…”

In order to analyze the influence of long-distance power transmission on the terminal voltage of agricultural network, this paper establishes the low voltage model of agricultural network based on the basic power flow model, and obtains the semi-quantitative relationship between the terminal voltage deviation and various factors by formula derivation. By introducing reference data for calculation, the influence of distance factor on the voltage reduction of the rural power grid is obtained. Under the same active and reactive power transmission conditions, the farm network voltage gradually decreases with the increase of the length of the agricultural network feeder. On the other hand, for the same feeder length, as the active power increases, the farm network voltage gradually decreases. As the reactive power increases, the voltage of the rural network gradually decreases. The trend of the rural power grid voltage with the reduction of the active power is greater than the reactive power, that is, the same percentage of the active power and the reactive power change. The active power has a more significant effect on the voltage reduction of the rural power grid. Therefore, the active, reactive and feeder lengths will have an impact on the terminal voltage of the rural network. By reducing the radiation range of the feeder, the terminal voltage of the rural network can be effectively improved.

This paper proposes a monitoring method of power dispatching automation master station based on clustering algorithm. Based on the application of history data, this method constructs multi-dimensional space vector, and generates operation state knowledge base by clustering algorithm. Real time data can be monitored and classified by using the generated knowledge base. The validity of the method is verified by a period of basic data. The results show that the method has better ability and accuracy to monitor power dispatching automation master station system, and it can provide reference for the selection of monitoring method of power dispatching automation master station.
