Generator power transmitter control method and system

Abstract

The invention discloses a generator power transmitter control method and system, and relates to the technical field of generator power transmitter control, the generator power transmitter control system comprises a generator automatic control cabinet, a monitoring device, a generator set and a power transmitter, and a generator power control system is configured in the generator automatic control cabinet. A generator monitoring system is arranged in the monitoring device, and a generator intelligent power transmitting device is arranged between the power transmitter and the monitoring device. According to the invention, the intelligent power transmitting device of the generator is researched and developed by researching the frequent irregular distortion such as overshoot, amplification, reverse and the like of a power plant and summarizing reasons; the problems that a unit control system is mistakenly adjusted due to transient errors such as overshoot and reverse of the transmitter in the system disturbance period, a power plant is fully stopped, and network-related safety is further affected are effectively solved.

Description

technical field [0001] The invention relates to the technical field of generator power transmitter control, in particular to a generator power transmitter control method and system. Background technique [0002] Generators are important equipment in modern life activities. Power transmitters are a convenient two-way system that converts input voltage and current signals into standard quantities that have a fixed function relationship with active power, reactive power, and power factor. The measuring device used by the secondary equipment. In order to ensure the stable operation of the generator, in the generator monitoring system, power transmitters are widely used to measure the power at the generator end and the load end, so that the monitoring system can analyze and process the data and take appropriate control. Therefore, the correctness and stability of the output signal of the power transmitter is of great significance to the stable operation of the generator. With t...

Problems solved by technology

[0003] In recent years, it has been found that when the main transformer is empty-charged (full-voltage impact) or the transmission line is grounded or short-circuited, a transient inrush current containing a large number of harmonics will be generated at the generator end, causing the conventional mode power transmitter to During transient disturbances, the output power signal produces irregular overshoot, amplification, reverse distortion and distortion, which causes the generator power control system to malfunction or disturb the action, causing unit power oscillation and even tripping events to occur from time to time, and Serious harm to the stable operation of the power grid
