Long-distance power transmission system capable of preventing self losses

Abstract

A long-distance power transmission system capable of preventing self losses comprises a power transmission line, a voltmeter, a single-chip microcomputer and a voltage compensation unit. The voltmeteris connected to the output end of the power transmission line, and the output end of the voltmeter is connected with the input end of the single-chip microcomputer; the single-chip microcomputer comprises an output port N1, the N1 is connected with the input end of the voltage compensation unit, and the output end of the voltage compensation unit is connected with the power transmission line. Theoutput voltage on the power transmission line is measured through the voltmeter, voltage data is output to the single-chip microcomputer, the voltage losses are obtained through analysis of the single-chip microcomputer, the single-chip microcomputer directly outputs a control signal from the N1, the control signal controls the compensation unit to compensate the voltage, and the problems that the self losses are generated in the power transmission process due to long-distance power transmission, and the output voltage becomes small and unstable due to the self losses are solved.

Description

technical field [0001] The invention relates to a power transmission system, in particular to a long-distance power transmission system capable of preventing self-loss. Background technique [0002] With the development of modern power systems, more and more large-capacity power plants far away from the load center have been built and put into operation. system. Among them, ultra-high voltage and long-distance transmission lines take on the task of connecting the receiving end system with large-capacity power plants in remote areas or power systems in different regions, and play a very important role. However, long-distance transmission lines will also bring many problems to the operation of the power system. Therefore, how to accurately, quickly and effectively adjust and monitor the operating characteristics of long-distance transmission lines and improve the steady-state characteristics and transient characteristics of the system has always been an important issue. an i...
