Abstract

Design of electrical system in the Faculty of Economics and Management Bogor Agricultural Institute was based guidance consisting of PUIL, SNI, as well as provisions of modern security and technology and aesthetic beauty. Design is also based on the relevant IEC standards, specifically IEC 60364. In the electrical system, it is necessary to pay attention to the conductor and safety factor to minimize power losses and drop voltage. Losses on the customer side due to drop voltage besides damaging electrical equipment is customers only can have a voltage less than 220 V. The distance between load panel and main panel is directly proportional to the drop voltage value, much farther the load panel to the main panel, resulting greater drop voltage value produced. The calculation of drop voltage based on total load, length, and area of conductor. To overcome the problems that occurred in this case study, the conductor uses 1.25 times the nominal current as a safety factor. The selection area of conductor can be said to be quite good with the farthest drop voltage value from SDP-TR is 0.89%. The total amount of electricity in the building is 158.33 kVA, assuming that if there is an additional 5-10 years, the total electric power and 15% of the others SDP is 182.04 kVA.

Abstract

Demand for electricity is increasing rapidly, the consequence of this is a threat to the stability of the electrical system, one of which is the voltage stability. FACTS or Flexible Alternating Current Transmission System is electronic equipment that is able to regulate electric power transmission that can be used to overcome stability problems. This research will analyze the use of Static Var Compensator (SVC) as one of the equipment from FACTS to overcome the stability of the most critical buses by using the 500 kV Java-Bali electricity system using PSAT. Results from using the power flow method in the 500 kV Java-Bali case show that the total active power generation is 12.144 p.u. and the total reactive power generation is 5.268 p.u. This value is obtained from the total addition of active power generation and reactive power of all plants in the 500 kV Java-Bali system. While the total active power load is worth 12.058 p.u. and the total reactive power load is 4.65 p.u. This value is obtained from the total load on each bus plus the total losses incurred on the line.
