Therefore, it is necessary to install an energy dissipation device on the busbar, so that the energy of the fault overvoltage can flow into the ground quickly and reliably. The trigger switch is applied in this energy dissipation device. The main electrode of the switch adopts a spiral groove structure, and the arc rotates around the edge of the electrode at high speed under the Lorentz force, which reduces the ablation of the electrode by the large current and improves the service life of the trigger switch. The magneto hydro dynamic (MHD) arc model is applied to simulate the arc movement characteristics. The influence of the main electrode’s diameter of central platform area in the trigger gap switch is investigated.

In addition, compared with the existing digital variable frequency method with current sensor, the proposed method estimates the inductor current through current observer which can be used in wide load range applications.

This paper gives an overview of HRES optimization by describing common optimization goals, techniques, and ways to model and simulate the systems.

In order to achieve this goal, the control system of HVDC must be capable of automatic discrimination and sequential control, selecting the correct strategy of reactive power control (RPC), which is essential for the stable operation of the HVDC system. Therefore, based on the operating conditions of the HVDC system and the switch configuration of the AC switch yard of the inverter station, the principle, process and interlocking conditions of automatic switching between different transmission modes are systematically analyzed. Effects on RPC, last breaker and the over voltage protection of AC busbar are researched.
