Description

Power line compensation control device
Technical Field
The application relates to the technical field of power line compensation, in particular to a power line compensation control device.
Background
With the continuous development of national economy in China, the electric power demand of various industries and the daily increase, and the electric load is larger and larger. Because of the large inductive load, the power factor of the power grid is reduced, the loss is increased, the energy utilization rate is reduced, and the power supply quality is reduced. Therefore, reactive compensation is improved, the power factor is improved, the power supply loss is reduced, and the power supply quality is improved, so that the method is always the problem to be solved.
The existing reactive dynamic compensation device consists of a controller, a thyristor, a parallel capacitor, a reactor, a zero-crossing trigger module, a discharge protection device and the like. The device tracks and measures the voltage, current, reactive power and power factor of the load in real time, analyzes the voltage, current, reactive power and power factor by a microcomputer, calculates reactive power and compares the reactive power with a preset value, calculates reactive power and compares the reactive power with the preset value, automatically selects compensation capacity capable of achieving the optimal compensation effect and gives out an instruction, and a zero-crossing trigger module judges the conduction moment of the bidirectional thyristor to realize quick and impact-free input into the parallel capacitor bank. However, the existing reactive compensation system device often has the phenomena of frequent damage to the capacitor bank and low input use rate, especially 10KV rural power grid power supply lines.
Because the power supply line of the 10KV rural power network is wide in distribution and long in line, particularly in inner Mongolia and eastern and western regions, a plurality of scattered reactive compensation points are generally required to be assembled on each line. However, at present, the switching of a capacitor is controlled automatically by adopting a single compensation point independently at home, and the defect is that a plurality of compensation switching control devices on the same line are heavy respectively and cannot perform unified scheduling and coordination control, and especially independent centralized compensation is realized. Although the power factor of the compensation point reaches more than 0.95 at each compensation point, more changes the reactive power flow distribution on the line, has low effect on reducing line loss and improving line terminal voltage, and is easy to generate the phenomena of over-compensation and reactive backflow.
Meanwhile, the single independent control device with wide distribution can bring great inconvenience to the management of reactive power optimization because the compensation real-time data and the working state are not transmitted back to the central computer in a centralized way.
