Cascaded HVDC gaseous circuit breaker performance using black box arc model

The development of renewable sources of electrical energy represents the main goal of the most countries. This energy has to be transmitted for a long distance for the utilization in populated areas. The need of high-voltage direct current circuit breakers represents the key of the development of high-voltage direct current transmission systems. High and extra high-voltage six sulfur hexafluoride circuit breakers need more than one interrupter to be stable during arc extinguishes, so it can be used in high-voltage systems as cascaded interrupters. In this article, the multi-break high-voltage direct current HVDC gaseous circuit breaker characteristic is investigated by employing Mayr and Cassie arc models. The influences of the models parameters on the arc interruption time are studied using MATLAB/Simulink program. It is concluded that the simulated results by employing black box arc models achieve a success in multi-break HVDC gaseous circuit breakers simulation. Employing BBAMs black box arc models has proved more flexibility to study the effect of different controlled and uncontrolled parameters on the multi-break high-voltage direct current gaseous circuit breaker HVDCGCB arcing time. That has proved more flexibility to study the effect of different controlled and uncontrolled parameters on the arcing time. The main contributions of this article in points can be summarized as employing black box arc models achieves a success in multi-break HVDC gaseous circuit breakers simulation, investigation of the influence of commutation parameters on the cascaded HVDC gaseous circuit breaker interrupter performance, the controlled and uncontrolled parameters affecting the arcing time of HVDCGCB has been studied, the impact of the fault resistance value on arcing time and the damping resistance influence on the transient recovery voltage are investigated, and additionally, the initial transient interruption and the Metal Oxide Varistor voltages are analyzed. From the investigated forty cases done to check the Mayr’s model validity in the HVDC CD simulation, it is found that the values of P and τ which give acceptable outputs are at τ = 10⁻⁶ s, and P in range of 10⁷ W to 10¹¹ W. The output of the case τ = 10⁻⁶ s, P = 10¹⁰ W, which is introduced in the paper has proved that when τ reached to 10⁻⁷ s the MOV current rises and drops and thereafter rises and gradually decreases. This may leads to CB failure Com parameters influence on the interrupter performance are investigated and proved good simulation of the gaseous circuit breaker interrupter.
