Problems solved by technology

In fact, the excitation system has real-time acquisition and data storage for the analog parameters and digital parameters that users are concerned about. The acquisition function of analog parameters and digital parameters in the wave recording system and the acquisition function of these parameters in the excitation system It is repetitive. In order to complete the fault recording function for the excitation system, the user must pay the high hardware cost again.

Abstract

The invention relates to a real-time excitation recording system, including an excitation real-time oscillography tool and an excitation record and playback tool. The excitation real-time oscillography tool is used for timely obtaining and processing recording data messages to obtain recording data of each sampling channel and carrying out oscillography and storage. The excitation record and playback tool is used for guiding in, playing back and analyzing the recording data. The real time collection capacity of an excitation controller is used as a data source, and by a network communication mode, the excitation real-time oscillography tool is used for completing extraction, connection and storage of data of each channel, and thus requirements for long-term real-time data recording are met, and control performances of the excitation controller cannot be influenced.

Description

technical field [0001] The invention relates to a system applied to excitation wave recording, which belongs to the technical field of measurement. Background technique [0002] The excitation system is an important part of the generator, which plays an important role in maintaining the constant voltage of the power system, adjusting the reactive power distribution among parallel operating units, and improving the static and dynamic stability of the power system. Power wave recording is one of the effective measures for equipment testing and fault analysis in the power system. Using the key analog parameters and digital parameters recorded by the wave recording system during the operation of the equipment, the cause of equipment failure can be qualitatively and quantitatively Complete the analysis of faults and event recall, improve the efficiency of fault investigation, improve and optimize equipment performance, and prevent the same fault from happening again. [0003] At...
