“…Previously, the authors applied the conventional control used for DC transmission (that is, the aforementioned receiving-side control) on both sides, and examined feedback frequency control in the initial stage of active power control on the sending side [4]. However, it required switching of the frequency control on the sending side in the transition from start-up to power generation.…”

“…In addition, some proposals have been made regarding power transmission from windfarms [2,3], and such systems are being investigated at the experimental level. As regards self-commutated HVDC transmission from windfarms, the authors studied the case in which there are no AC sources other than wind power generators on the windfarm side [4,5]; no other detailed reports are available.…”

SUMMARYHVDC consisting of self-commutated inverters is able to be applied for power transmission connecting from a remote large windfarm to a weak AC system. Most self-commutated HVDC is applied for connection between two AC systems that have synchronous power sources, but it is not suitable for a windfarm that consists of induction generators without synchronous power source. This paper presents new control for the self-commutated HVDC system connected to a large windfarm of induction generators. The effect of the proposed control is shown by EMTP simulation.

“…In [6], it has been suggested that VSC are preferred for multi terminal DC (MTDC) because power flow can be reversed without changing the polarity of dc link voltage. In weak power system short circuit can be prevented by blocking of signals of wind farm converters [7]. In [8], fault study has been done using empirical mode decomposition which requires phasor measurement unit (PMU) or communication network which is very expensive.…”

Voltage source converter (VSC) based high voltage direct current (HVDC) transmission is most suited for the wind farm as it allows flexibility for reactive power control in multi-terminal transmission lines and transmits low power over smaller distance. In this work, a novel method has been proposed to detect the fault, identify the section of faults and classify the pole of the fault in DC transmission lines fed from onshore wind farm. In the proposed scheme, voltage signal from rectifier end terminal is extracted with sampling frequency of 1 kHz given as input to the detection, classification and section discrimination module. In this work, severe AC faults are also considered for section discrimination. Proposed method uses fuzzy inference system (FIS) to carry out all relaying task. The reach setting of the relay is 99.9% of the transmission line. Besides, the protection covers and discriminates the grounding fault with fault resistance up to 300 X. Considering the results of the proposed method it can be used effectively in real power network.

“…We have proposed basic control for such a system that enabled stable power transmission of all generated power. (Noro, 2002, Tanomura, 2006 The generated power fluctuates depending on changes in wind velocity; therefore, power levelling is desirable for the receiving power system to relax stress on the generator governors. This paper proposes power levelling controls that are demonstrated by digital simulation using the ATPDraw5 program (Hoidalen, 2007).…”
