Frequency Electric Field

In ultra-high voltage transmission system, the electrostatic induction generated by power frequency electric field will exerts negative effects on the electrical automation equipment within the substation and, in particular, will leads long-term harm to staffs’ health. However, researches of electric field environment in ultra-high voltage transmission system merely concentrate on calculating the electric field intensity caused by three-phase limited length wire or three-phase infinite wire within the transmission, without considering the method of calculating half-infinite wire which represents “one end is fixed, while the other end is infinite length’s wire”. Consequently, a new method named “Charge Simulation-Genetic Algorithm (CS-GA) method” which can efficiently calculate power frequency electric field inside of the substation is proposed in the paper. In CS-GA method, the effective calculating length is determined by genetic algorithm method’s optimization, which in other words, half-infinite length wire is substituted for limited length wire in calculating the electric field intensity. The simulation results indicate that CS-GA method is a relatively accurate, efficient and reasonable way on calculating the power frequency electric field inside of the substation.

Distribution of electrical energy from a plant to a substation or from a substation to other substations usually uses a transmission line. In Bali, type of transmission line that is usually implemented is SUTT 150 kV. The magnitude of the applied voltage is an attempt to reduce power loss for long distance distribution. However, distributing electrical energy with increasing stress affects the increase of electric field around the transmission line. The negative impact of electricity distribution has been an environmental problem for PT. PLN (Persero), especially where there is conversion from an open area to be a residential. This problem has been the main reason for conducting this research. IRPA / INIRC recommendation states that exposure time is not limited to the electric field effect in work environment and public area including a residential area at frequency of 50/60 Hz is 5 kV/m.  This recommendation is in accordance with SNI 04-6950-2003, on Threshold Limit Values ??Electric Field under SUTT and high-voltage wires. The first problem of this research is how large the intensity of the electric field between two poles of SUTT 150 kV with vertical and horizontal constructions which are built side by side? The second problem is what the characteristic of the electric field intensity between the two poles which are built side by side? From the analysis, it can be seen that the intensity of the electric field that occurs between the conductor of the vertical and horizontal pole configurations are still below the IRPA/INIRC and SNI 04-6950-2003 recommendation i.e. 1 up to 1.5 kV/m and at a distance of 18 meters to 25 meters there is an interaction of electric field intensity that occurs at these two configurations.
