VI. REAL SYSTEM
The real system was modeled in PSAT is shown in Fig. 4 with
two hydro generating stations Idukki and Sabarigiri, thermal
station at Kayamkulam, diesel generating station at
Brahmapuram and the wind farms at Ramakkelmedu. The
model consists of fifteen buses including load buses and PV
buses. The Pallom substation consists of a 40 MVAR
compensator which is shown in the model. This system was
analyzed for small signal stability and voltage stability. The
maximum loading point was found by plotting P-V curves for
variations in loads at the buses. As in the test system the
optimal location for the placement of STATCOM was found
with the help of P-V curve.
