To make better use of local generators' dynamic var reserve to improve short-term voltage stability (STVS), this paper proposes an integrated high side var-voltage control (IHSV C) for power plants in receiving-end power systems. The IHSV C consists of a plant-level multi-machine var coordinator (MMVC) and several unit-level high side voltage controllers (HSVCs). MMVC coordinates the reactive power output among generators and provides control parameters for HSVCs, while HSVCs can maintain the voltage of a pre-defined voltage control point (VCP) by regulating the voltage reference of the excitation control of each generator. Therefore, when the system suffers a serious fault, IHSV C can drive the generators to provide stronger var support. Consequently, the voltage stability can be improved. A conceptual model of the receiving-end power system in China Southern Power Grid (CSG) is established, and the IHSV C has been validated through a simulation analysis on the system. Both time-domain simulation results and the voltage sag severity index (VSSI) have fully demonstrated its performance. Therefore IHSV C offers a new and effective approach to improve STVS of receiving-end power systems.Index Terms-Dynamic var reserve, high side voltage control, receiving-end power systems, short-term voltage stability, var/voltage control.

“…One is on its role in maintaining static voltage stability, which is verified in single-machine infinite-bus (SMIB) power systems [13]- [16]. The other is on its usage for steady-state reactive power distribution among multiple generators in a power plant [17], [18]. The latter is not associated with transient control.…”

“…Ovako dug period probnog rada bio je neophodan da bi se potvrdio kvalitet odziva GRPRS pri različitim nivoima potrošnje u EES. Rezultati su prikazani u [12], [13], [14], [15] i [16]. U ovom radu su dati odzivi koji verifikuju osnovne funkcije GRPRS: regulacija napona sabirnica elektrane i automatsko održavanje maksimalne reaktivne rezerve elektrane pri promeni uslova u mreži i promeni opterećenja.…”

Kratak sadržaj: U radu je prikazan uređaj za grupnu regulaciju pobude i reaktivnih snaga u termoelektrani. U radu su prvo obrazloženi potreba i opravdanost uvođenja ovakvih uređaja na elektrane. Opisane su funkcije uređaja za grupnu regulaciju pobude i reaktivnih snaga u elektrani, zatim je data teorijska osnova razvoja uređaja. Postignute performanse uređaja ilustrovane su nizom odziva tokova reaktivnih snaga i napona sabirnica nakon ugradnje uređaja u najveću termoelektranu u Srbiji, TE "Nikola tesla A".Ključne reči: termoelektrana, naponsko-reaktivna regulacija, grupna regulacija pobude i reaktivnih snaga UvodU cilju prevazilaženja nedostataka ručnog upravljanja naponima i reaktivnim snagama, razvijeni su sistemi za automatsko upravljanje naponima u elektroenergetskim sistemima (EES) sa namerom da se unaprede sigurnost, smanje gubici i olakša proces upravljanja EES [1]- [5]. Automatizacijom upravljanja naponima i reaktivnim snagama na nivou sistema predviđeno je da dispečer prenosne mreže postavi vrednosti napona u određenim čvorovima sistema i da se reaktivne snage generatora koji utiču na napone posmatranih čvorova postave automatski na potrebne vrednosti. Na ovaj način se eliminiše kašnjenje zbog učešća operatera u izvršenju komandi dispečera prenosne mreže. Ukoliko se i raspodela reaktivnog opterećenja među generatorima vrši koordinisano prema željenoj optimizacionoj funkciji, postiže se koordinisana naponsko-reaktivna regulacija.85
