Problems solved by technology

When a new protection function needs to be added, the entire protection unit becomes more complicated
At the same time, due to the limitation of the hardware manufacturing process level, the reliability and anti-interference performance of the traditional protection unit are limited
In addition, due to the limitation of data processing capabilities, it is difficult to give full play to the advantages of many protection algorithms. In many functions, only preliminary approximate results can be given, and the realization of algorithms and principles is subject to certain restrictions.

Description

technical field [0001] The invention relates to a protection unit in the field of electrical engineering science, in particular to a protection unit of a communication series capacitor compensation device with dual DSP and HPI interfaces. 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, with the increase of power transmission distance, its transmission capacity is more and more restricted, and series compensation is one of the important means to solve this problem and improve the power transmission capacity of trans...
