Shunt Capacitor

AbstractThis paper proposes a novel shunt capacitor (SC) based voltage stability method for a power system operation. The integration of distributed generators e.g. wind and PV powers to the grid, and fluctuations nature of load power cause the attention of voltage stability management for a power system operation and planning. The SC based proposed method improves the voltage stability by using the flow of active and reactive powers in the transmission line. The Voltagestability index (VSI) is utilized for the voltage stability analysis. The SC is installed at the load bus so that it can inject a proper amount of reactive power for ensuring the voltage stability of power system. The proposed method is investigated in the IEEE-14 bus test system. Simulation results are compared with the non-SC based method. Extensive simulation analyses have been done by the MATLAB/Simulink software.

Simulation Results

The theory of the excavator’s hydraulic system was elaborated in the paper taking a 20t hybrid hydraulic excavator produced by a domestic company for example. The rotary movement of the hybrid hydraulic excavator was achieved by a newly developed electric motor, fuel consumption could be reduced as the result of the speed inhibition when the excavator standby. The modeling of excavator’s hydraulic system, front-end attachments and revolving frame were built on the AMESim platform according to the installation and actual sizes of the hydraulic components. By setting the parameters of every component in the model, mechanical- electronic- hydraulic integrated simulation was achieved. The paper focused on the solutions of hydraulic system’s pressure fluctuation and poor simulation results of front-end attachments. As a conclusion, appropriate solutions and simulation results were proposed to improve the precision.
