Voltage dropphenomena that can be caused by various conditions such as heavy loads, accidents or other disturbances must be avoided. This study examines the voltage stability of the 150 kV Sulbagsel system integrated with PLTB. The method used is the New Voltage Stability Index (NVSI) which is a hybrid of the Fast Voltage Stability Index (FVSI) with the Line Stability Index (Lmn). The results of the study indicate that the 150 kV Sulbagsel system integrated with PLTB is stable, namely the stability value is less than 1. The most stable system stability value is on the network from PLTD Tello to Tello, which is 0.002. While the most unstable network system is from the Sidrap PLTB network to the Makale PLTA network, namely the stability index is 0.029. ## Keywords - Control theory (sociology) - Stability (learning theory) - Voltage - Electric power system - Power (physics) - Index (typography) - Engineering - Computer science - Line (geometry) - Wind power - Environmental science - Power network --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
