“…A multiple feed in test system is then established for HVDC system based on real operating conditions, with which various operating statuses of HVDC transmission system are simulated and several typical faults of HVDC transmission system are tested. The simulation results show that the model agrees very well with the real operating conditions of the HVDC transmission system [5].…”

In this study, the modelling methods are compared in terms of their accuracy and modelling simplicity for different types of components. And the principle of the equivalent circuit model is obtained from reference and is used in the proposed equivalent circuit models of other equipment of HVDC converter stations. Then, all the models are connected into an HVDC system, and simulations are conducted to verify the validity of the proposed model. A comparison with the traditional modelling method shows that the proposed method is more effective for studying entire HVDC converter stations, and is also better suited for equipment building and simulating. Simulation results show that the model is effective and acceptable.

“…The average value model of two-level VSC proposed in literature [6] only considers the external characteristics of VSC converter, which improves the simulation speed. Literature [7] proposed dynamic/extended harmonic domain method, Gensior's research [8] proposed state space average method, Literature [9] proposed generalized state space average method, and Literature [10] established a dynamic phasor model of VSC converter based on dynamic phasor method. In addition to the modeling of power electronic converter, there are some methods for the overall modeling of photovoltaic power station, but the overall equivalence of photovoltaic power station is difficult, and the accuracy of the equivalent results is not high, can not cover all working conditions, can not take into account the simulation accuracy and simulation speed.…”

It has important engineering value for electromagnetic transient simulation of photovoltaic power generation unit. The current mainstream electromagnetic transient simulation methods of photovoltaic power generation units can not meet the current needs. In order to improve the simulation speed and simulation accuracy of photovoltaic power generation unit, this paper uses the principle of matrix splitting and mixed integration to decouple the VSC converter in photovoltaic power generation unit, and writes a program to compare with the detailed model built in PSCAD to verify the validity of the electromagnetic transient simulation model of photovoltaic power generation unit proposed in this paper.

“…In the simulation of asymmetric fault and waveform distortion, the non-fundamental component is generated, and the simulation result is not accurate enough. Based on the time-varying Fourier coefficients, the dynamic phasors method is used to model LCC-HVDC [4][5][6][7]. This model can reflect the dynamic behavior of the system, but it is an average-value model.…”

Abstract:In order to improve the simulation speed of the AC/DC hybrid grid, the inductance/capacitance (L/C) switch model for line-commutated converter of high-voltage direct current (LCC-HVDC) is presented in this study. The time domain modeling method is used to analyze the circuit of L/C switch model for the six-pulse system in LCC-HVDC in a switching period. A parameter setting method of L/C switch model is proposed considering the transient response, the steady state performance, switching losses and simulation error of the switch. The inductance/capacitance (L/C) switch model for LCC-HVDC has the advantage of keeping the admittance matrix unchanged regardless of the change of switching state, which improves the simulation efficiency. Finally, the validity of the parameter setting method is verified. Compared with the test results of PSCAD/EMTDC, the accuracy of the proposed LCC-HVDC simulation model is proved. The model is suitable for real-time or offline simulation of AC/DC hybrid grid.
