Problems solved by technology

[0005] At present, when power supply enterprises find low-voltage problems, they usually simply attribute the reasons to three reasons: transformer overload, too thin wire diameter, and too large power supply radius. There are no clear and quantitative analysis tools and methods

Embodiment Construction

[0042] According to the general principles of power system analysis, the low-voltage analysis adopts the analysis sequence from the power supply end to the power receiving end. A station area first obtains power from the 10kV line by the distribution transformer, and after it becomes 400V, it is sent to the load through the low-voltage line. Therefore, from the three levels of 10kV lines, distribution transformers, and low-voltage lines, we can comprehensively analyze the causes of low voltage, formulate corresponding control measures for the problems existing in the station area, and evaluate the economics of the control measures.

[0043] The invention provides an intelligent control method for low-voltage station areas based on a forward-backward generation algorithm, which solves the technical problem of lack of effective low-voltage analysis and control in the prior art.

[0044] The purpose of the present invention is achieved through the following technical solutions:

Abstract

The invention provides a low-voltage platform region intelligent management method based on a forward-backward substitution algorithm. The low-voltage platform region intelligent management method comprises the following steps: 1, determining a platform region with a low-voltage phenomenon; 2, collecting original data; 3, drawing a picture and setting electric element parameters; 4, carrying out load flow calculation; 5, analyzing low-voltage factors; and 6, carrying out low-voltage management and economic evaluation. According to the low-voltage platform region intelligent management method, a position with the low-voltage phenomenon in the platform region is found by algorithm calculation according to front end voltage and tail end voltage of the platform region; one set of intelligent management measures with best economical efficiency can be generated by combining an actual low-voltage phenomenon solving measure; and effective helps for platform region analysis and project approval are provided for field personnel.

Description

technical field [0001] The invention relates to an intelligent management method for a low-voltage station area based on a push-back algorithm. Background technique [0002] With the rapid development of the rural economy and the continuous improvement of farmers' living standards, the nature of farmers' electricity consumption has undergone fundamental changes, and the demand for electricity has entered a higher level. However, the long-term mechanism for the development of the power grid has not yet been established, and the comprehensive rectification system measures for low-voltage control are lacking. It is urgent to quickly and efficiently control the low-voltage problem in rural areas in the shortest time from both management and technology aspects, so as to ensure "new countryside, new power, and new services" "Smoothly promoted to meet the demand for electricity for rural economic and social development. [0003] Focus on improving the voltage quality of rural low-...
