Buduk feeder is a 20 Kv medium voltage distribution system that gets power supplyfrom the ship's substation and crosses large coastal areas and rice fields and is prone to naturalphenomena such as lightning. During 2018 there were 3 lightning disturbances. Based on thesedata, it is necessary to analyze the distribution channel failure at Buduk feeders, so thecontinuity of the distribution channel can be better. The performance of the Spike System iswhen a lightning surge occurs on the distribution channel, the Spike System directly transmitsthe lightning strike to the ground. Based on the data analysis, it is necessary to add a Spikeprotection system to the Buduk Feeder to maintain the continuity of electric power.The methodused in this research is to collect data in the form of a single line diagram, disturbance data dueto lightning strikes at Buduk feeders. Next, compared the Buduk feed line before Spikeinstallation and after spike installation. First, analysis of technical data and the channelperformance before spike installation.

The transmission line of 150 kV between GIS (Gas Insulated Switchgear) Bandara Ngurah Rai and GI Nusa Dua needs to be concerned further due to the high number of VIP customers supplied by the GIS Bandara Ngurah Rai. The location of transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is also located in the southern area of Bali in which according to the data of BMKG in 2018, it was recorded that 15.000-30.000 lightning strike occurred in the southern area of Bali. One of the devices used to protect the equipment from lightning surge is lightning arrester. Lightning arrester which is used in the network of GIS Bandara Ngurah Rai to GI Nusa Dua is placed on Cable head 60. The transmission line of GIS Bandara Ngurah Rai with GI Nusa Dua is connected by an overhead line of 8.5 km and an underground cable of 2.02 km, which is connected by terminating on Cable head 60. The distance between the Airport GIS transformer and the lightning arrester is 2.02 km, therefore it needs to be studied further in order to find out whether the protection generated by the lightning arrester has been optimal or not. The result showed that the arrester with an installation distance of 2020 meters from the transformer is still able to cut the lightning surges by producing the sparkover voltage value of 605.12 kv. Accordingly, the result of sparkover voltage exceeds the sparkover voltage of the arrester in the number of 577kv, however the voltage is still within the tolerance range of the sparkover voltage of the arrester.

The need for electricity in Bali is increasing along with the growth of technology and developmentin Bali, so the quality of electricity distribution to customers must also be improved. This study took anexample from the 2018 case, Palapa Feeder used 2 reclosers which had an index value that did not meetthe standard of the reliability index value. When the Palapa Feeder only used LBS, SAIFI value was2.1055 and SAIDI was 7.2960, when the LBS was changed to recloser the SAIFI value was 1.203 andSAIDI was 4.091. When a recloser was added again the SAIFI value became 1.016 and SAIDI became3.4088. The use of 2 reclosers on a feeder is less effective, because if they are placed at a close distance,then there will be two devices work simultaneously when there is a disturbance so that the area which isnot affected by the disturbance will also experience a power outage. Therefore it is necessary to design arecloser placement point in order to obtain lower reliability index value in order to meet the PLN standard(SPLN) No. 68-2: 1986, World Class Company standards, World Class Service standards, and alsoobtained the optimum recloser location and more efficient.The design of recloser placement is carried out using the Quantum Genetic Algorithm method,which is an evolutionary algorithm based on the concept of quantum bits (qubits). The purpose of thismethod is to minimize the SAIDI and SAIFI value in order to obtain lower reliability index and meet thestandards in order to obtain an optimum recloser location. The results of the recloser placement designusing the QGA method show that the local optimum recloser location is in section 2 at point 56 with thehighest fitness value is 4.9715 and a SAIDI value is 1.8951 decreased by 44.4% and SAIFI value is 0.9978decreased by 1, 78%, and it is proven that the recloser placement design using the QGA method hassucceeded in obtaining local optimum with better SAIDI SAIFI index results and has met the PLN (SPLN)standard No. 68-2: 1986 with SAIDI 3,33 and SAIFI 1,2 and also meets World Class Company and WorldClass Service standards with SAIFI 3 (times/customer/year) and SAIDI 1,66 (hours/customer/year).

The Sanda feeder is supplied by Antosari Substation through transformer unit II and ithas 3 reclosers, they are pempatan recloser,bangsing recloser and palisan recloser. Based onthe 2017 disturbance fault recapitulation data from PT PLN (Persero) Bali, it has been phasephaseand 1-phase ground short circuit in Sanda feeders almost every month. One of theproblems that often occurs in Sanda Feeders is when a phase-phase and 1-phase ground faultoccurs at the end of the feeder network and causes simultaneous trips to the recloser at thebase of feeder network, causing the Sanda feeder relay to blackout. This shows the systemneed to analyze the evaluation of the coordination settings for the OCR and GFR protectionsystem on the recloser and Sanda Feeder relays to minimize disturbances so as to improveservice continuity. The analysis and simuation results represent that, the existing settingconditions of OCR and GFR has coincide coordination curves and the grading time is still below0.3 seconds. The calculation and simulation of OCR and GFR that are carried out show that theprotection system works selectively in the absence of coincide coordinating curves and a timegrading value above 0.3 seconds according to the IEC 60255 standard.

The disruption of the electric power system due to overcurrent causes a trip to the 3rd generator of pesanggaran power plant . This causes a decrease in frequency due to the system losing its supply. Frequency interference can be detected automatically with UFR (Under Frequency Relay). The working principle of UFR is to compare the value of the system frequency and the value of the frequency setting. The comparison will determine how much load is released to balance the generator supply. This study analyzes UFR performance at Pesanggaran Substation by simulating a case of the generator being released so as to produce a decreased system frequency state. The method used is by comparing the ETAP simulation results and calculation results. The results of the comparison obtained the system recovery time when the conditions (gen1 tripped), (gen1 and gen2 tripped), and (gen1, gen2, and gen3 tripped), each is 1.171s; 4,531s; and 4,514s.
