ANALYSIS OF POWER TRANSFER ON TRANSMISSION CHANNELS 150 KV FROM GARDU INDUK AIR ANYIR TO GARDU INDUK SUNGAILIAT PLN BANGKA AREA
The availability of sufficient and quality electrical energy is a demand that must be fulfilled by PT. PLN (Persero). Distribution of electricity through the 150 kV transmission line with a relatively long distance and using aluminum type conductive wire always experiences changes in current and voltage, giving rise to the ability to send electricity power unstable. Other influences can also be obtained from changes in power factor and phase angle. The method used is the method of analyzing equations in the form of hyperbolis. In this study shows that the power transfer ability is influenced by phase angles. The maximum active power transfer capability is 1962.71 kW on VS which is 150∠75⁰ and VR which is 150∠0⁰ with phase angle difference is 75⁰. Whereas in VS = 150∠75⁰ and VR = 145∠0⁰ the transfer ability of active power is 1911.97 kW with the difference in the same phase angle of 75⁰. This study shows that the transfer ability of active power is influenced by voltage. The maximum active power transfer capability for VR values = 150∠0⁰ at VS which is constant, which is 150∠90⁰ is 2134.49 kW. Whereas for the VR value = 145∠0 VS at VS which is constant which is 150∠90⁰ is equal to 2078.03 kW.
