Grounding system is an important role in a substation operation, it should be designed by adjusting the distance of the grid and the length of the ground rod to get the most optimal combination of quality and cost. This paper aims to design the model of grounding system by determining permissible touch voltages and permissible step voltages, and simulating the design model using CymGRD software on 275/150 kV Sigli Substation. The result shows that a 50 kg person can safety be inside and outside of the yard. The step and touch potential transfers are acceptable within the yards with a minimum 0.1 m layer of crushed rocks. The step potential level is acceptable along the troughs.

The novel idea of this work is the simultaneous use of different sensors for partial discharge (PD) measurement and monitoring of medium voltage cable connectors. The measurement with one sensor or with several identical sensors may entail inaccuracies, caused by noise or external interferences, etc. To increase the validity and reliability of the PD measurements, various sensors could be fused into a multi-sensor system. In this study, six different sensors are investigated. The well-known HFCT sensor for the inductive PD measurement is compared with the capacitive approach. A new low-cost capacitive sensor is introduced, which is fixed around the cable connector. Capacitive PD measurements are realized over the bushing of the switchgear, as well. Electromagnetic PD detection is implemented using a loop antenna and leaky feeder cables. The latter mentioned sensor is a new approach for PD measurements in High-Voltage (HV). The last sensor is an ohmic sensor, which is realized using the earthing cable of the cable connector. The proper installation of sensors on the cable connectors plays a key role in PD detection and is therefore discussed in detail. If the electric field of cable connectors is not carefully regarded, the sensors themselves may produce discharges. That is why the electrical field of the cable connector is investigated using a 3D FEM simulation in the first step. Row measurements of different 10 kV cable connectors with PD faults are performed in an MV switchgear. The sensors are correctly installed, and a self-developed low-cost monitoring system records the PD activity. The measurements are discussed in detail. Using well-known PD analysis patterns, the effectivity of the system is shown.

Many researchers are investigating the feasibility of using polypropylene in HVDC cables. To understand the basic electrical properties of nanocomposite polypropylene, this work investigates the influence of nanostructuring on DC breakdown strength, life under periodic voltage polarity reversals and space charge accumulation properties. Preliminary results show that unfilled samples feature higher charge accumulation, lower breakdown strength, and shorter life than the nanocomposite counterpart. Based on these results, nanostructured dielectrics can give an important improvement in electrical insulation properties.

PV development and its integration to the power grid were growing rapidly, these rapid developments due to sustainability and environmental issue. In order to support the development, all researchers and engineers worldwide were conducted studies related to the PV development. Currently, most of PV development studies only consider an aspect. Developers consider irradiation, land acquisition, road access, and proximity with the load. Government consider the PV’s potential and existing power system readiness. Utility considers the technical effect of PV integration based on Grid Code limitation. In order to have a complete view of PV development, this study considers 3 aspects, such as mapping the potential of PV, the readiness of the system by statistical methods, and determining the capacity & location of PV plants that meet Grid Code. The results of the PV development study which considered several aspects would provide benefits to PV development. This study will be applied to the island of Bali as a case study.

This paper reports electric field intensity minimization in a three-phase 150 kV GIS spacer with aim to reduce the maximum electric field intensity (Emax) in the spacer, especially around the triple junction area, where conductor, spacer, and SF6 gas meet. Some modifications on the spacer material are conducted to minimize the maximum value of electric field intensity in it, including applying Functional Graded Material (FGM) method, which is a relatively new technique that is proven to reduce electric field intensity in the most effective way. An already designed three- phase 150 kV GIS spacer made from epoxy resin with relative permittivity of 3.5 is provided as the initial model. A double layer FGM method is used in this research where the spacer material is modified to have two different materials combined, consisting of epoxy resin with relative permittivity of 3.5 which is placed in the middle area of the spacer, and Titanium Dioxide (TiO2) with relative permittivity of 8.4 which is placed around the triple junction area. Each modification is performed through simulation using Comsol Multiphysics software for electric field distribution simulation by modeling the initial spacer designed in 3D, and by applying three-phase supply voltage with Vmax of 150 kV to the phase conductors, the electric field distribution specifically the maximum electric field intensity for each voltage phase angle is monitored. The result shows that the Emax in the spacer which is originally 138 kV/cm can be reduced from 10% up to 59%. The most significant reduction in electric field intensity is given by the FGM method, resulting Emax of 56 kV/cm.

Light Rail Transit (LRT) is a future public transportation that is being developed in Indonesia, especially in Jakarta and Palembang. In Palembang, this public transportation has 13 stations built quite high. The height of the stations can reach 25 to 30 meters. This high-rise buildings will be an easy target for lightning strikes in the area such as Palembang. This is because Palembang is located in the area where the Monsoon wind reversal occurs. This Monsoon wind reversal affects the density of lightning strikes especially in tropical country surrounded by the sea such as Indonesia. The impact of damage caused by lightning strike is enormous. Analysis of lightning protection systems to be applied on LRT stations in Indonesia, especially in Palembang area, is carried out to evaluate the existing protection system. This research analyzes and discusses grounding, bonding, shielding, surge protection for internal protection system and the new innovative Extended Mast Terminal (EMT) for external protection system. This research will provide conclusion for lightning protection system that is suitable to be applied in Indonesia.

Borneo is one of Island in Indonesia besides Sumatera, Sulawesi, Java, and Papua. It has three subsystems, West Borneo, East - North Borneo, and South - Center Borneo. There are a lot of option to increase the power, one of the solutions is transferring the power between subsystems. This paper will expain the study of interconnecting two subsystemss, East - North Borneo with South - Center Borneo with the impacts to the system. Nowadays, that two subsystems is weak, which total generation of East – North Borneo is 400 MW and the South - Center Borneo is 500 MW, both of the subsystems has limited spinning reserved (10%), the spread of the load is not evenly converging in some area with long distance transmission and there is only one generation as the base load carrier for each subsystem. In 2015, the developing of electric generation in South - Center Borneo will be growth rapidly than East - North Borneo, whereas the load itself lighter. So there is a planning to interconnect between two subsystems to get realiblity and economical value, because of some diesel generation that was full of fuel will be switched off. This stability study includes power flow, voltage stability, small signal stability and transient stability. This study uses power system simulation software Digsilent. The output of the study is a technical recommendation for The headquarter of state electricity company as a policy taker about this interconnecting plan.

Sulselbar power flow condition indicates the existing of buses voltage under specified standards which is determined. The operation of the Sulselbar electrical system consists of 44 buses and the power loss is 80.104 MW due to the non-optimal location of the reactive power. One of the solution to overcome the problems is the installation of Static Var Compensator (SVC) in Sulselbar transmission system. Several methods were conducted and improved to optimize the location of SVC. In this paper, the installation of SVC is using Inertia Weight Particle Swarm Optimization (IWPSO) which is the improvement of PSO. The optimization result shows that the Sulselbar transmission system require 4 location of SVC which are at bus 5 with 45.7 MVAr, bus 17 with 34.06 MVAr, bus 31 with 50.8 MVAr, and bus 40 with 120 MVAr. The result of the SVC installation is that the bus average raised 3.3% from 0.961 pu to 0.994 pu which also leads to power losses reduction on average of 9.14% from 80.104 MW to 72.777 MW.

Artificial Intelligence (AI) has reached many life aspects, including in power engineering field. In power engineering itself, there is a challenge in improving the transmission system quality to make it more reliable. Partial Discharge as one of the main problem that makes the High Voltage Apparatus face the possibility of breakdown. AI would have a low error rate compared to humans and also has incredible precision, accuracy, and speed. Artificial Neural Network (ANN) one of AI types is an adaptive non-linear programming meaning ANN is very suitable for use on sensitive, non-fixed and dynamic systems such as PD signals. This study will analyze the performance of the implementation of artificial neural networks to recognize the types of Partial Discharge (PD) of experimental result gained by author. Important information in the process of pattern recognition and assessment of PD signals is the phase pattern, the amount of charge (q), the number of PD signal appearances, the amplitude max PD, and the min PD amplitude. The phase pattern and the amount of charge (q) can represent the pattern of the PD signal, while the max amplitude, min amplitude, and the number of appearances of the PD signal (n) can represent the level of PD signal vulnerability. These five quantities will be used as the component of artificial neural networks. Then the network that has been created will be used for the process of pattern recognition and assessment of PD signals in the application made.

In power engineering itself, there is a challenge in improving the transmission system quality to make it more reliable. Partial Discharge as one of the main problem that makes the High Voltage Apparatus face the possibility of breakdown. AI would have a low error rate compared to humans and also has incredible precision, accuracy, and speed. Artificial Neural Network (ANN) one of AI types is an adaptive non-linear programming meaning ANN is very suitable for use on sensitive, non-fixed and dynamic systems such as PD signals. This study will analyze the performance of the implementation of artificial neural networks to recognize the types of Partial Discharge (PD) of experimental result gained by author.
