Power system protection is one of the main element of modern energy management concept. The main task of these systems is to deactivate the faulty element or network part as soon as possible. The protection relays, called intelligent electronic devices, also have different functions than these basic functions. However, overcurrent, distance and differential protection are still used as the three basic components. In this study, current studies on these relays for coordination of the protection system have been analyzed. The research topic is limited to the main functions of the relays. Further study will examine the tasks that these relays have in providing data to the energy management system. It can also focus on the concept of wide area protection, event recording and modern communication protocols.

“…Relay simulation in Power Systems is an activity recognized by technical literature thirty years ago as an option to analyze its operation and adjusting parameters [6], transient analysis [7], and modeling using computer sciences for distance relays [8]. Since then, relays modeling is a complementary tool to prove and adjust operation schemes [9,10]. The mho type distance relay development and analysis consider several polarization methods for transmission-lines scheme protections [10][11][12][13].…”

This paper presents a mho distance relay simulation based on the phase comparison technique using a typical electrical power systems analysis software for two cases: when the operation state is close to the static voltage limit and during a dynamic perturbation in the system. The paper evaluates the impedance variations caused by complex voltage values, the mho polarization, and the comparator operating region into the complex plane. In addition, the paper found the information for the dynamic perturbations from the outputs considering a mid-term stability program. The simulation of the mho-phase comparator in the static voltage proximity limit detects unit distance elements with impedance measured close to reach the threshold in the steady-state. Dynamic mho simulations in the complex plane are successfully tested by plotting time phase difference curves on the comparator input signals. Relay programmers can use these curves to analyze other phase comparators applications and the corresponding models in the complex plane.

“…Its working principle of realizing the isolation of fault and nonfault lines in power grid is that the energy provided by the operating mechanism is transferred to the interrupting element by driving rod when the probe sensing system fails, and the interrupting element realizes the opening and closing of the circuit by the transferred energy. Once the high voltage circuit breaker breaks down in the power operation, the loss will be enormous [2]. Huang et al [3] proposed a mechanical fault diagnosis method for high voltage circuit breaker based on wavelet time-frequency entropy and one-class support vector machine (SVM), optimized the parameters using particle swarm algorithm, and verified the accuracy of the method through experiments.…”

The development of power grid system not only increases voltage and capacity, but also increases power risk. This paper briefly introduces the feature extraction method of the vibration signal of high voltage circuit breaker and support vector machine (SVM) algorithm and then analyzed the high voltage circuit breaker in three states: normal operation, fixed screw loosening and falling of opening spring, using the SVM based on the above feature extraction method. The results showed that the accuracy and precision rates of fault identification of circuit breaker were the highest by using the wavelet packet energy entropy extraction features, the false alarm rate was the lowest, and the detection time was the shortest.
