The Electrical power transmission and distribution power traces performs important roles in Power System strategies it has to reap the crucial continuity of carrier of power supply to the cease users. The power transmission traces join the producing stations and cargo centers. The possibility of fault occurrences in transmission traces could be very high. Since faults can destabilize the electricity device it should be remote without delay for recovery of electricity supply. It is fault evaluation could be very critical difficulty in power approach engineering just so to clean faults fast and repair electricity deliver as quickly as feasible with minimal interruption. In this paper gives a literature evaluate of electricity transmission line faults detection.

Transmission line is a very absolute thing in an electric power system. In the distribution of electricity from generating centers to loads (consummers), where the distance is quite far it is done through the transmission line. Transmission channels those are generally used based on construction are the lattice type and steel pole. The transmission channel has a safe limit against other objects around it according to the standard set. The air transmission line uses a TACSR (Thermal Aluminium Conductor Steel Reinforce) conductor which has a working capacity with temperatures up to 1500C. Based on calculations when the distance is 212m with a  temperature of  1500C the value of the roof is 9,40m. When the distance is 173m with a  temperature of  1500C the maximum value of the roof is 7.8m. When The condition of the temperature and the length of the span affect the value of the roof the greater of the temperature and the length of the span, so the greater of the resistance.ABSTRAK:Saluran transmisi adalah suatu hal yang sangat mutlak dalam suatu sistem tenaga listrik. Dalam penyaluran tenaga listrik dari pusat-pusat pembangkit ke beban (konsumen), dimana jaraknya cukup jauh maka dilakukan lewat saluran transmisi. Saluran transmisi yang umum digunakan berdasarkan konstruksinya adalah tipe lattice dan steel pole. Saluran transmisi ini memiliki batas aman terhadap obyek lain yang ada di sekitarnya sesuai standar yang ditetapkan. Saluran transmisi udara menggunakan konduktor jenis TACSR (Thermal Aluminium Conductor Steel Reinforced) yang memiliki kemampuan kerja dengan suhu sampai 1500C. Berdasarkan perhitungan pada saat jarak span 212 m dan dengan suhu 1500C andongan maksimumnya bernilai 9,40 m. Pada saat jarak 173 m dan dengan suhu 1500C andongan maksimalnya 7,8m. Pada saat jarak 233 m dengan suhu 1500C andongan maksimumnya adalah 10,58m. Keadaan suhu dan panjang span mempengaruhi nilai andongan, semakin besar suhu dan panjang span maka nilai andongan akan semakin besar.

With the integration of highly permeable renewable energy to the grid at different levels (transmission, distribution and grid-connected), the volatility on both sides (source side and load side) leading to bidirectional power flow in the power grid complicates the control mechanism. In order to ensure the real-time power balance, energy exchange, higher energy utilization efficiency and stability maintenance in the electric power system, this paper proposes an integrated application of blockchain technology on energy routers at transmission and distribution networks with increased renewable energy penetration. This paper focuses on the safe and stable operation of a highly penetrated renewable energy grid-connected power system and its operation. It also demonstrates a blockchain-based negotiation model with weakly centralized scenarios for “source-network-load” collaborative scheduling operations; secondly, the QoS (quality of service) index of energy flow control and energy router node doubly-fed stability control model were designed. Further, it also introduces the MOPSO (multi-objective particle swarm optimization) algorithm for power output optimization of multienergy power generation; Thirdly, based on the blockchain underlying architecture and load prediction value constraints, this paper puts forward the optimization mechanism and control flow of autonomous energy coordination of b2u (bottom-up) between router nodes of transmission and distribution network based on blockchain.

This work proposes a new method for fault diagnosis in electric power systems based on neural modules. With this method the diagnosis is performed by assigning a neural module for each type of component comprising the electric power system, whether it is a transmission line, bus or transformer. The neural modules for buses and transformers comprise two diagnostic levels which take into consideration the logic states of switches and relays, both internal and back-up, with the exception of the neural module for transmission lines which also has a third diagnostic level which takes into account the oscillograms of fault voltages and currents as well as the frequency spectrums of these oscillograms, in order to verify if the transmission line had in fact been subjected to a fault. One important advantage of the diagnostic system proposed is that its implementation does not require the use of a network configurator for the system; it does not depend on the size of the power network nor does it require retraining of the neural modules if the power network increases in size, making its application possible to only one component, a specific area, or the whole context of the power system.

Overload Capacity

During the operation of the electric power system, there is often a need to overload its individual elements (generators, power transformers, overhead and cable power lines, switching electric devices) for a period lasting from several dozens of minutes to a day. The overloads can be caused by intentional disconnection of parallel elements of the system because of scheduled preventive repairs, post-accident disconnections, as well as an unexpected increase in electricity consumption due to the impact of various factors. The overload capacity of the system elements makes it possible to increase operational reliability of power supply to consumers without additional expenditures while maintaining, in most cases, the almost normal service life of electrical equipment. Oil-filled transformers have the greatest potential overload capacity power, which makes it possible to consider them as a significant source of increasing the capacity of the transmission and distribution networks of the electric power system. Excessive over-current of power oil-filled transformers significantly reduces reliability and reduces their normal service life. This is due to the accelerated process of wear of the insulation material of the transfer windings as a result of overheating of the transformer oil, that causes structural changes and, as a consequence, to mechanical damage to the insulation of the windings; the latter can cause an electrical puncture. On the other hand, underestimation of the permissible overload of transformers might result in economic losses due to under-produced products when the functioning of the part of the transformers connected in parallel are ceased for scheduled preventive maintenance or as a result of forced emergency shutdowns. Therefore, there is a need to assess the potential of reasonable increase in the throughput capacity of the electrical network and, accordingly, the reliability of the power supply system, taking into account the requirements for the permissible loads of transformers when the electrical network and various operating modes are being designed.
