In the world, special attention is paid to determining the stability margins of electrical systems in connection with the high growth rates of demand for electricity. In this regard, special attention is paid to research aimed at improving the stability and dynamic properties of electric power systems, including through the use of modern control methods based on intelligent systems. The application of HVDC and FACTS transmission technologies have added new control methods to the power system, increased the throughput of electrical networks, and improved monitoring capabilities. Power system stabilizers (PSS) are traditionally used to damp electromechanical low-frequency oscillations in the frequency range 0.2–1.5 Hz. This paper proposes the use of thyristor-controlled series capacitors (TCSC) control systems as a oscillations damper.

Dunyoda elektr energiyasiga bo‘lgan talabning yuqori sur‘atlarda o‘sishi munosabati bilan elektr tizimlarining barqarorlik zaxiralarini aniqlashga alohida e‘tibor qaratilmoqda. HVDC va FACTS uzatish texnologiyalarining qo‘llanilishi energotizimga yangi boshqaruv usullarini qo‘shdi, elektr tarmoqlarining o‘tkazuvchanlik qobiliyatini oshirdi va monitoring imkoniyatlarini yaxshiladi. PSS (power system stabilizers) energotizim stabilizatorlari an‘anaviy ravishda 0,2–1,5 Gs chastotalar diapazonidagi elektromexanik past chastotali tebranishlarni so‘ndirish uchun qo‘llaniladi. Ushbu ishda TCSC (thyristor-controlled series capacitors) ketma-ket kompensatsiya qurilmalarining boshqaruv tizimlaridan tebranishlar dempferi sifatida foydalanish taklif etilgan.
