Opis:: W artykule podano genezę wprowadzenia sterowników uelastyczniających przesył prądu przemiennego FACTS (ang. Flexible AC Transmission System). Podano ich definicję i podział. Ustalono przyczyny poszczególnych zakłóceń dla stanów ustalonych jak i przejściowych oraz opisano działania, jak i urządzenia konieczne do ich ograniczenia. Podano także krajowe korzyści ze stosowania sterowników FACTS oraz związane z nimi wyzwania w przyszłości.
The article provides the genesis of Flexible AC Transmission System (FACTS). It is given a definition and methods of division this controllers, taking into account the design, the used connectors and the destination. For fixed and transient states it is given sources of interferences, which actions should to be taken to mitigate the effects of disturbances, and by which devices can this be accomplished. The article specified a examples of application of FACTS controllers in Poland and tasks which still are waiting for solution. The research directions related to FACTS are given. In conclusion, it is assumed, that further applications of these drivers in power networks are unavoidable. Selecting a type of controller to task at a given site of network should be preceded by a digital simulation to see its impact on other system parameters. The specificity of European networks is different from place where these controllers mainly applied, the coordination of the automatic protection of power network near these controllers belongs to local power dispatchers, and the differents between this systems exclude simple copying of solutions. The research show a different degree of influence of the controllers on the automatic protection.

Opis:: Transmission line loss minimization in a power system is an important research issue and it can be achieved by means of reactive power compensation. The unscheduled increment of load in a power system has driven the system to experience stressed conditions. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The significance and use of Flexible AC Transmission System (FACTS) devices and capacitor placement is in order to alleviate the voltage profile decay problem. The optimal value of compensating devices equires proper optimization technique, able to search the optimal solution with less computational burden. This paper presents a technique to provide simultaneous or individual controls of basic system parameter like transmission voltage, impedance and phase angle, thereby controlling the transmitted power using Unified Power Flow Controller (UPFC) based on Bacterial Foraging (BF) algorithm. Voltage stability level of the system is defined on the Fast Voltage Stability Index (FVSI) of the lines. The IEEE 14-bus system is used as the test system to demonstrate the applicability and efficiency of the proposed system. The test result showed that the ocation of UPFC improves the voltage profile and also minimize the real power loss.

Opis:: The distance relay using the transmission line impedance measurement identifies the type and location of the fault. However, any other factors that cause the failure of the measured impedance, makes the relay detect the fault in incorrect location or do not detect the fault at all. One of these factors is the fault resistance which directly increases the measured impedance by the relay. Another factor that indirectly alters the impedance of the transmission line is static synchronous compensator (STATCOM). When a fault happens, current injection by the STATCOM changes the measured signals by the relay and thus makes the calculated impedance incorrect. In this paper, a method is provided based on the combination of distance and differential protection. Firstly, from the current data of buses, faulted transmission line is detected. Then using the presented algorithm, the fault location is calculated on the transmission line. The basis of the algorithm is on the active power calculation of the buses. Fault resistance is calculated from the active powers and its effect will be deducted from calculated impedance by the algorithm. Furthermore, with choosing data of appropriate bus, STATCOM effect is eliminated, and fault location will be obtained.
