specific Embodiment approach

[0013] The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

[0014] A low-voltage comprehensive control device for rural power grids, the device includes 10kv line reactive power compensation equipment 2, 0.4kv line reactive power compensation equipment 4, 10kv line on-load voltage regulator 3 and control center 1, 10kv line on-load voltage regulation The 10kv line reactive power compensation equipment is parallel connected to each section of the line, the 0.4kv line reactive power compensation equipment is parallel connected to each end of the line, and the control center is installed in the control room of the substation. The control center communicates with the controllers of the 10kv line reactive power compensation equipment, the 0.4kv line reactive power compensation equipment, and the 10kv line on-load voltage regulator through GPRS.

[0015] The reactive power compensation equipment 4 of the 0.4kv lin...

Abstract

The invention provides a rural power network low voltage comprehensive treatment control device and method. The device comprises 10kv circuit reactive-load compensation equipment, 0.4kv circuit reactive-load compensation equipment, a 10kv circuit on-load voltage regulator and a control center. The rural power network low voltage comprehensive treatment control method is implemented by means of the rural power network low voltage comprehensive treatment control device, and the problems that in existing devices, no communication exists, unicontrol is carried out, the cost is high, and the voltage treatment effect is not obvious are well solved.

Description

technical field [0001] The invention belongs to the field of low-voltage control equipment, and relates to a low-voltage comprehensive control device and method for rural power grids. Background technique [0002] In recent years, with the development of the economy, the load of the rural power grid has increased dramatically, and the electricity demand of users has continued to increase. However, the lines of the rural power grid in my country are too long, the wire diameter is too thin, and the booster and compensation equipment are insufficient, resulting in the terminal voltage and power of the rural power grid. If the factor is too low, it will seriously affect the normal power consumption of rural grid users, so a series of voltage regulation measures must be taken to ensure that the voltage meets the requirements of the grid. If the grid user's voltage is too low and the power factor is too low, the equipment will fail to start and the equipment will not operate normal...
