Modelling and simulation of voltage source converter-based interphase power controller as fault-current limiter and power flow controller

The Interline Power Flow Controller (IPFC) is a voltage-source-converter (VSC)-based flexible ac transmission system (FACTS) controller for series compensation in a multiline transmission system of a substation. The capability of injecting series voltages with controllable magnitude and phase angle makes it a powerful tool for better utilization of existing transmission lines in a multiline transmission system. IPFC is used to regulate active and reactive power flow in a multiline system, usually. In this paper, a control method for IPFC is proposed to control magnitude and phase angle of one sending bus of a substation. All degrees of freedom of IPFC and decoupled synchronous frame concept are used in the proposed control structure. Simulation results in Matlab/Simulink are presented to show the capability of IPFC in compensating the bus voltage.

Goi-tentsioko korronte zuzeneko (ingelesez, High Voltage Direct Current HVDC) garraio-sistemak gero eta garrantzitsuagoak dira sistema elektrikoan, onura ekonomiko eta teknikoak direla eta. Hala ere, akatsen bat gertatzen denean, korrontea eteteak oraindik ere erronka izaten jarraitzen du HVDC sareetan. Desiragarriak ez diren korronteak eteteko, korronte zuzeneko etengailuak erabil daitezke, baina horien gaitasuna mugatua da. Egoera hala izanik, akats-korronteen mugagailuak (ingelesez, Fault Current Limiter FCL) dira proposamenik egokiena akats-korronteak maneiagarriagoak diren balioetara txikitzeko; hartara, sistema elektrikoaren garraio-ahalmena handitu daiteke, ekipamendua aldatu beharrik gabe. Sarean aldez aurretik legokeen ekipamendua gai izango litzateke korronte berriak kudeatzeko eta sistema era eraginkorrean babesteko FCLen erabilpenaz. Artikulu honetan, FCL tresnen ezaugarri orokorrak eta sailkapena aurkezten dira. Ondoren, egoera solidoko FCLa erabili da maila anizkoitzeko bihurgailudun (ingelesez, Modular Multilevel Converter MMC) VSC-HVDC (ingelesez, Voltage Source Converter) sistema batean, eta horren jokaera azaltzen da simulazio bidez.

In this paper, a hybrid high voltage direct current transmission system containing a line commutated converter and a voltage source converter is developed. To enhance the robustness of the hybrid transmission system against direct current short-circuit faults, resistive-type superconducting fault current limiters are applied, and the effectiveness of this approach is assessed. Related mathematical models are built, and the theoretical functions of the proposed approach are expounded. According to the transient simulations in MATLAB software, the results demonstrate that: (i) The superconducting fault current limiter at the voltage source converter station enables to very efficiently mitigate the fault transients, and owns an enhanced current-limiting ability for handling the short-line faults. (ii) The superconducting fault current limiter at the line commutated converter station is able to mildly limit the fault current and alleviate the voltage drop, and its working performance has a low sensitivity to the fault location. At the end of the study, a brief scheme design of the resistive-type superconducting fault current limiters is achieved. In conclusion, the application feasibility of the proposed approach is well confirmed.

Abstract Faults in the DC circuit constitute one of the main limitations of voltage source converter VSC-HVDC systems, as the high fault currents can damage seriously the converters. In this article, a new design for a fault current limiter (FCL) is proposed, which is capable of limiting the fault current as well as interrupting it, isolating the DC grid. The operation of the proposed FCL is analysed and verified with the most usual faults that can occur in overhead lines.

This paper proposes a non-superconducting bridge-type fault current limiter (BFCL) as a potential solution to the fault problems of doubly fed induction generator (DFIG) integrated voltage source converter high-voltage DC (VSC-HVDC) transmission systems. As the VSC-HVDC and DFIG systems are vulnerable to AC/DC faults, a BFCL controller is developed to insert sizeable impedance during the inception of system disturbances. In the proposed control scheme, constant capacitor voltage is maintained by the stator VSC (SVSC) controller, while current extraction or injection is achieved by rotor VSC (RVSC) controller. Current control mode-based active and reactive power controllers for an HVDC system are developed. Balanced and different unbalanced faults are applied in the system to show the effectiveness of the proposed BFCL solution. A DFIG wind-based VSC-HVDC system, BFCL, and their controllers are implemented in a real time digital simulator (RTDS). The performance of the proposed BFCL control strategy in DFIG-based VSC-HVDC system is compared with a series dynamic braking resistor (SDBR). Comparative RTDS implementation results show that the proposed BFCL control strategy is very efficient in improving system fault ride through (FRT) capability and outperforms SDBR in all cases considered.
