“…Zbog toga automatizacija upravljanja naponsko-reaktivnim prilikama u sistemu postaje sve značajnija. Hijerarhijska automatska kontrola napona realizovana je u nekoliko zemalja [1], [2], [3]. Najveći nedostatak realizovanih sistema je zatvorena povratna petlja po reaktivnoj snazi [2], [3].…”

“…Hijerarhijska automatska kontrola napona realizovana je u nekoliko zemalja [1], [2], [3]. Najveći nedostatak realizovanih sistema je zatvorena povratna petlja po reaktivnoj snazi [2], [3]. Zato se u veoma složenom francuskom EES uvodi regulacija pilot čvora koja obuhvata sve generatore u zoni i koordiniše njihovo dejstvo [1].…”

“…Razvoj tog uređaja je podrazumevao da se dobro prouče svi nivoi upravljanja naponima jer GRPRS se nalazi na spoju elektrane i sistema. Najveća opasnost ovih sistema je pojava oscilacija reaktivne snage između generatora i između tih elektrana [1] [,2], [3]. Razvijeno je zato rešenje koje ne zatvara povratnu spregu po reaktivnoj snazi na generatoru direktno iznad naponske petlje.…”

Kratak sadržaj: U radu se razmatra mogućnost direktnog uključenja uređaja za grupnu regulaciju pobude i reaktivnih snaga u automatizovani sistem upravljanja naponima u elektroenergetskom sistemu. Grupni regulator pobude i reaktivnih snaga (GRPRS) predstavlja sistem kojim se vrši automatsko upravljanje reaktivnim režimom elektrane i raspodela reaktivnog opterećenja među generatorima paralelno spregnutim preko blok transformatora i uključenim u grupni rad. Realizacijom sistema za grupnu regulaciju reaktivne snage postiže se ravnomerna raspodela reaktivnog opterećenja agregata koji učestvuju u grupnoj regulaciji, a prema mogućnostima koje definišu pogonske karte pojedinih agregata. Grupnu regulaciju agregata u okviru elektrane potrebno je realizovati kako bi se uravnotežila eksploatacija agregata i kako bi se obezbedilo da se agregati u grupnoj regulaciji ravnomerno odazivaju na poremećaje u elektroenergetskom sistemu, kako bi se obezbedio rad agregata unutar pogonskog dijagrama pri različitim radnim uslovima u mreži (uslovi izuzetno niskih i izuzetno visokih napona) kao i radi adekvatnog definisanja naponsko-reaktivne karakteristike u tački priključenja elektrane na prenosnu mrežu. Sa stanovišta elektroenergetskog sistema implementacija GRPRS omogućava: i) praktičnu realizaciju sekundarne regulacije napona u sistemu, ii) maksimalno iskorišćenje raspoložive reaktivne rezerve u sistemu što doprinosi udaljavanju od granice naponske stabilnosti sistema, iii) ocenu doprinosa svakog generatora u pružanju pomoćne usluge regulacije napona. GRPRS ima potpuni uvid u reaktivnu i naponsku rezervu svakog generatora, prati stanje u mreži kroz napon na sabirnicama tako da se može koristiti da u realnom vremenu dostavlja operatoru sistema cenu i tarifnu zonu proizvedene 1

“…This system controls the terminal voltage of the generator by Automatic Voltage Regulator (AVR) in the generation level, whereas controls the key bus voltage by control generators in a control regional level. The concept of the key bus and the control area are based on interrelation between a load bus and another load buses by electrical distance [4][5][6][7][8][9]. The on-line voltage control using full SCADA information is implemented in the bulk power system.…”

-This paper deals with shunt compensation to eliminate voltage violation and enhance transfer capability, which is motivated towards implementation in the Korean power system. The optimal shunt compensation algorithm has demonstrated its effectiveness in terms of voltage accuracy and reducing the number of actions of reactive power compensating devices. The main shunt compensation devices are capacitor and reactor. Effects of control devices are evaluated by cost computations. The control objective at present is to keep the voltage profile of a key bus within constraints with minimum switching cost. A robust control strategy is proposed to make the control feasible and optimal for a set of power-flow cases that may occurs important event from system. Case studies with metropolitan area of the Korean power system are presented to illustrate the method.

“…Under current situation, the system operator of Korea has been interested in hierarchical voltage control, which was initially proposed in several European countries. They have firstly proposed a secondary voltage control which can control the voltages of generators through controlling reactive powers to maintain the pilot bus voltage in a voltage control area [1][2][3][4][5][6][7][8][9]. The desired voltages on the pilot buses come from the results of optimal voltage-var planning in the energy management system of independent system operators.…”

-This paper presents the results of field tests on Voltage Management System (VMS) using hybrid voltage control, which utilizes coordinated controls of various reactive power resources such as generators, FACTS and switched shunt devices to regulate the pilot bus voltage in a voltage control area. It also includes the results of performance test on RTDS-based test bed in order to validate the VMS before installing it in Jeju power system. The main purpose of the system is adequately to regulate the reactive power reserve of key generators in a normal condition with coordination of discrete shunt devices such as condensers and reactors so that the reserves can avoid voltage collapse in emergency state in Jeju system. Field tests in the automatic mode of VMS operation are included in steady-states and transient states. Finally, by the successful operation of VMS in Jeju power system, the VMS is proved to effectively control system voltage profiles in steady-state condition, increase system MVAR reserves and improve system reliability for pre-and post-contingency.
