“…We used the PSCAD/EMTDC platform to verify the validity and feasibility of the TFI methods based on active power RMS value and twisty beat frequency when transition resistance values were 0 and 100 Ω.

“…Consequently, wind power‐generated electric power is frequently delivered through long‐distance, high‐voltage transmission lines. Shunt reactors are often used on these lines to compensate for their distribution capacitance . Wind farms in China are typically built at the end of a grid; hence, a wind power outgoing line (WPO line) may be the only power transmission channel to the grid.…”

This paper proposes two novel adaptive single‐phase auto‐reclosing (ASPAR) schemes for shunt reactors‐compensated wind power outgoing (WPO) line. After extinction of a fault on a single phase‐tripped WPO line, due to the existence of shunt reactors and distributed capacitors, a free frequency component will emerge in the tripped faulty phase, which will make faulty phase active power calculated with instantaneous power algorithm have a bigger magnitude and more frequency components. According to these characteristics, transient fault identification (TFI) methods based on active power root mean square (RMS) value and twisty beat frequency were put forward. Subsequently, in view of abovementioned TFI methods, ASPAR schemes for a shunt reactors‐compensated WPO line based on faulty phase active power characteristics were established. Simulation experiments, which were conducted using the software PSCAD/EMTDC, verified that the proposed ASPAR schemes can distinguish transient faults from permanent ones rapidly and reliably. The experiments also proved that the proposed adaptive single‐phase reclosing schemes can minimize the influence of changes in fault location and transition resistance and, thus, are suitable for the inconsistent output power of a wind farm and the complex working condition of an outgoing line.

“…Shunt reactors are widely used in high voltage transmission lines to improve power system stability and line voltage profile regulation [23]. The methods presented in [24][25][26][27][28][29][30] are effective for shunt compensation transmission lines. In these methods, the beat frequency generated after the quenching of the secondary arc was used to detect the quenching of the secondary arc.…”

“…In [26], the differences of faulty phase terminal voltage between the two fault states after arc extinction was utilized as a criterion to detect fault nature and clearance. In [27,28], the instantaneous power algorithm was utilized to compute faulty phase reactive and active power, respectively, using local voltage and current measurements. Increasing faulty phase reactive or active power after secondary arc extinction was used to detect arc extinction for shunt compensated transmission lines.…”

This paper presents a reliable and fast index to detect the instant of arc extinction for adaptive single-pole automatic reclosing (ASPAR). The proposed method is a simple technique for ASPAR on shunt compensated transmission lines using the Hilbert–Huang Transform (HHT). The HHT method is a combination of the empirical mode decomposition (EMD) and the Hilbert transform (HT). The first intrinsic mode function (IMF1) decomposed by EMD, which contains high frequencies of the faulty phase voltage, was used to calculate the proposed index. HT calculates the first IMF spectrum in the time-frequency domain. The presented index is the sum of all frequency contents below 55 Hz, which remains very low until the fault clearance. The proposed method uses a global threshold level and therefore no adjustment is needed for different transmission systems. This method is effective for various system configurations including different fault locations, line loading, and various shunt reactor configurations, designs, compensation rates, and placement. The performance of the method was verified using 324 test cases simulated in electromagnetic transient program (EMTP) related to a 345 kV transmission line. For all the test cases, the algorithm successfully operated with an average reclosing time delay of 32 ms.
