“…An example of conventional PS detection methods can be found in the Siemens 7SA522 relay. The PS detection algorithm of this relay is based on continuous impedance calculation [44][45][46][47]. In this relay, the main PS detection criterion is that the input impedance has to exhibit three properties: monotony, continuity, and smoothness.…”

“…Finally, for the smoothness property, the relay computes the successive derivatives of R and X using (11) and (12) to ensure that they are lower than a preset threshold. This condition ensures that the input impedance locus has a uniform motion [44][45][46]…”

A wide area monitoring system (WAMS) with reliable telecommunication infrastructure can be expanded and enhanced with additional protection and control functionalities using synchronized phasor data measurements. With that aim, we have developed a multifunctional line protection (MFLP) model with both system and back-up protection functions. Theoretical premises based on transmission and relay protection system knowledge, together with the experience gathered from the operation of existing wide area systems, were used to develop the proposed model. Four main groups of simulation scenarios were defined in order to test the newly implemented functions. The results of the simulation process confirm the assumptions underlying the design of our MFLP module. Simulation results are then used for definition of the protection criteria required for implementation of the wide area protection algorithm in a control center. Conclusions drawn from the protection responses of the proposed algorithm that strengthen the algorithm design process are elaborated in the paper. The main contribution of the paper is the design and development of a centralized MFLP algorithm based on synchronized phasor data that is able to issue a trip command to a circuit breaker before an out-of-step condition occurs.

“…Basically, OOSP can be based on different principles of operation: current, distance and angular OOSP [1]. At present, each design organization is developing its own OOSP operation algorithm based on one or another concept of detection of out-of-step operation, which undoubtedly increases the reliability of the power system operation [2][3][4][5][6][7][8][9][10][11][12][13][14]. However, OOSP algorithms simultaneously control many parameters of the electric power network, and therefore are very difficult to implement, and checking their settings in the process of commissioning is labor-consuming.…”

The article addressed the issue of commissioning task that must take place before putting out-ofstep protection into operation. Most of the developers of digital out-of-step protection devices utilize control of impedance vector locus parameter during transient in a power system to detect its out-of-step operation, however checking the setting of such protection in the field conditions using existing means is often a challenging work. To facilitate the commissioning of such devices and provide means to automatize the process so as to rid of human factor the authors suggest means of simulating impedance vector locus with the desired parameters on the complex plane to check distance out-of-step protection. The means for checking current-oscillation based out-of-step protection is also considered. The results of a transient simulation representing instantaneous values of currents and voltages are saved in the international oscillography recording format COMTRADE, which makes it possible to carry out comprehensive verification of emergency control equipment using any kind of testing equipment that is able to generate the corresponding electrical signals stored in such format.
