Abstract

The invention discloses a voltage stabilizing system for long-distance power transmission, which includes a power transmission line, a voltmeter, a single-chip microcomputer and a voltage compensation unit. The single-chip microcomputer includes an output port N1 and an output port N2, the N1 is connected to the input end of the voltage compensation unit, the output end of the transformer outputs the voltage, and the N2 directly outputs the voltage, and the present invention measures the output voltage on the power transmission line by a voltmeter, Output this voltage data to the single-chip microcomputer, and after the analysis of the single-chip microcomputer, it is known whether the voltage meets the requirements. If it meets the requirements, the single-chip computer outputs the voltage directly from N2. If it does not meet the requirements, it is output from N1 to the voltage compensation unit for compensation to the required voltage. Output, to solve the problem that the traditional long-distance output voltage is directly obtained from the power transmission line, and the obtained voltage is the voltage after loss, resulting in an unstable voltage at the end.

Description

technical field [0001] The invention relates to a power transmission system, in particular to a voltage stabilization system for long-distance power transmission. 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 importa...
