“…T HE most common and inevitable disturbances of the power system are usually faults and sudden load changes. These disturbances lead to transient instability depending on their severity [1]. Power system stability plays a vital role in the reliable operation of the power system.…”

“…Power swings can be synchronous (synchronous generators do not lose synchronism) or asynchronous (synchronous generators lose synchronism) depending on the severity of the disturbances [3]. At the generation side, when the generator or group of generators is exposed to the asyn-chronous power swing, instability may occur, and the generator experiences the pole slipping, which can cause stress on the system and pole (coil) [1]. Deep synchronous or asynchronous power swings are accompanied by massive changes in voltages and currents, which pose a serious threat to power system operation.…”

The existing out-of-step (OOS) protection schemes have proven to be deficient in the prevention of significant outages. OOS protection schemes must not operate in stable power swing, and rapidly isolate an asynchronous generator or group of generators from the rest of the power system in case of unstable power swing. The paper proposes a novel phasor measurement unit (PMU) incorporating a polygon-shaped graphical algorithm for OOS protection of the synchronous generator. The unique PMU-based logic works further to classify the type of swing once the graphical scheme detects it, which can identify the complex power swing produced in the modern power system. The proposed algorithm can take the correct relaying decision in the event of power swing due to renewable energy integration, load encroachment, and transient faults. In this paper, the original and modified Kundur two-area system with a power system stabilizer (PSS) is used to test the proposed algorithm. In the end, it provides assessment results of the proposed relay on the Indian power system during the blackout in July 2012. The results demonstrate that the proposed algorithm is fast, accurate, and adaptive in the modern power system and shows better performance than the existing OOS protection schemes.

“…Power swing (PS) is a transient phenomenon in the power systems that interferes with operational zones of distance relays and leads to mal‐operation of these relays and disconnection of healthy lines of the power system. This might cause network instability and eventually overall system blackouts, as happened in 2003–2012 in countries such as Malaysia, Italy, Brazil, and India [1–5]. In the distance relays, a function called PS blocking (PSB) is used [6] to prevent mal‐operation during PS events.…”

Distance relays are susceptible to maloperation during postfault power oscillations in the system. This unintended operation of relays may lead to power system blackout. It is due to their inability to distinguish a stable from an unstable power swing and to take a tripping decision appropriately. This research paper proposes a fast and wavelet energy-based method to detect stable and unstable power swings for distance relays. The proposed method computes the angular velocity of an equivalent machine developed from the measurements available at a bus. The energy in the low frequency band of the equivalent machine angular velocity will assist the tripping decisions of transmission line relays during power swings. Compared to the conventional method using blinders, the advantage of this method is that it requires less hardware and less time to know whether the resulting power oscillations after fault clearing are going to be stable or not. The performance of the proposed method has been evaluated on 5-bus system, WSCC 9-bus system, and IEEE 14-bus and 30-bus systems considering different test scenarios. The results show that using this method improves the performance of distance relays in detecting stable and unstable power swings.
