Transient wave-recording playback system of series capacitor compensation device or fault current limiter device

Abstract

The invention relates to a transient wave-recording playback system of a series capacitor compensation device or a fault current limiter device. The system comprises a transient wave-recording playback card and a transient wave-recording playback managing machine. The transient wave-recording playback card comprises a digital signal processor (DSP), an embedded processor, a communication interface and a wave-recording Ethernet. The DSP and the embedded processor are connected through the communication interface. The embedded processor is connected in the wave-recording Ethernet. An embedded operation system is adopted in the transient wave-recording playback card. The transient wave-recording playback managing machine comprises a transient wave-recording managing machine of a spacing layer and a transient wave-recording managing machine of a station control layer. The transient wave-recording managing machine of the spacing layer and the transient wave-recording managing machine of the station control layer are connected with the wave-recording Ethernet respectively. The system disclosed by the invention has a playback function, a strong communication function and a strong distributive wave-recording and storing function and is in conformity with the implement requirements of the modern digital transformer station. The system can be also used for other flexible alternating-current power transmission devices.

Description

technical field [0001] The invention relates to a transient recording and replaying system in the field of flexible alternating current transmission (FACTS) of a power system, in particular to a transient recording and replaying system of a series compensation device or a fault current limiter device. Background technique [0002] The series capacitor compensation technology of the AC transmission system (referred to as series compensation) is to connect the power capacitor in series in the AC transmission line to compensate the partial inductive impedance of the AC transmission line, so as to increase the transmission capacity of the line, improve the stability of the system, reduce the loss of the network, and save energy. investment purposes. In long-distance and large-capacity power transmission systems, as the transmission distance increases, its transmission capacity is increasingly limited, and series compensation is one of the important means to solve this problem an...

AI Technical Summary

Problems solved by technology

[0007] At present, the transient wave recording systems of other devices such as series refills at home and abroad have the following defects: 1. The functions of the wave recording systems lacking the playback function are very incomplete, and some even have no wave recording function, which is difficult for operation maintenance and debugging analysis. 2. Generally, there are only independent transient recording devices for substations, but no embedded transient recording devices for distributed applications, so that the entire recording system is not powerful enough and the structure is not flexible enough; 3 1. The communication function is weak and cannot meet the implementation conditions of digital substations and IEC61850 standards; 4. The distributed storage function is weak or lacking; 5. The data collection and processing speed of the processor and the functions that can be realized cannot meet the growing user needs
