Description

technical field [0001] The invention relates to the technical field of miniature dynamic simulation of electric power system, in particular to a comprehensive experimental cabinet for miniature simulation of power system transmission lines. Background technique [0002] The simulation methods of power system transmission lines are divided into physical simulation methods and software simulation methods. [0003] The physical simulation method is based on the law of similarity, and the simulated components and the prototype transmission line have the same physical characteristics and mathematical parameters (per unit value). This method is to shrink the actual transmission line according to a certain ratio. The simulation process does not require the similarity of the electromagnetic field in space, nor does it require the propagation speed of the wave process to be similar along the line. It only requires that the voltage and current at certain points on the line change with...

AI Technical Summary

Problems solved by technology

In the traditional physical simulation method, there are certain problems in the transmission line simulation: the simulated transmission line unit and the simulated line unit are erected separately, and the external connection is complicated, which leads to the messy experimental platform; the high voltage level of the experiment reduces the safety and feasibility of the experiment; the simulation The unit is bulky, the interface is not uniform, and it is very difficult to change the topology of the transmission line network; the monitoring and control unit includes voltage transformers, current transformers, power meters, power factor meters, circuit breakers, etc. and the difficulty of coordinated control

The above reasons make it difficult for traditional analog transmission lines to meet the simulation requirements of modern power system transmission lines.
