Decision-Making and Support Tools for Design of Transmission Systems

Transmission systems are crucial components of many machines and mechanisms. Ken Hurst (1998) highlights that whether you are designing power plants, cars, or washing machines, the power transmission system is an integral component responsible for product success or failure. The components that comprise a power transmission system include those that transfer power directly (coupling and shaft), speed and torque multiplication components (gears, belt drives, etc.), and the related mechanisms (clutches, brakes, etc.; see Freeman & Velinsky, 1995). Transmission system design is a multistage iterative process of sequential generation and modification of design decisions. These decisions define in many respects the technical and economic characteristics of future products. Searching for suitable design decisions is a highly complex and time-consuming problem due to the necessity to consider and analyze many heterogeneous functional, technical, and economic factors. However, extensive computations, including solving very complex optimization tasks, are needed. As a rule, the design procedures are provided only by a very competent and experienced designer. With ever more complex and combinatorial decisions to be made, even the best designer will need competent design support, of which there is little. Therefore, the design of transmission systems is a wide open area for development and application of decision-making and decision support technologies.

Power Transmission Systems

Resonant power transmission systems are designed for power supply to remote consumers of small and medium power, as well as for lighting of premises and territories. The systems include frequency conversion devices, power lines, and reverse voltage conversion devices to the required voltage for the consumer. This system can be used for transmitting electricity via power lines to Wi-Fi access points. (Research purpose) The research purpose is in analyzing LPWAN networks, developing a set of equipment for resonant power transmission, calculating the project cost and describing the operation of the resonant system set. (Materials and methods) During the study, the next materials, equipment, and devices were used: a three-phase rectifier with a capacitor filter, an electronic transmission control circuit, power switches and a resonant oscillating circuit (transformer). (Results and discussion) To design and manufacture the installation, authors used the principle of operation of the resonant power transmission system based on the use of two transformers, operating at a frequency of 5-15 kilohertz, and single-wire line between them with a line voltage of 1-10 kilovolts when operating in a resonant mode at which the system operates at a frequency of 7-9 kilohertz, and the voltage in the transmission line of 1500 volts allows to transmit electricity through the single-wire transmission line with a capacity of up to 8,000 watts at a distance of 1.5 kilometers. Authors analyzed the features of the LPWAN network and developed a set of equipment for resonant power transmission, transmitting and receiving units. (Conclusions) The scientific and practical significance of the results is in: a set of resonant power transmission systems, calculated the cost of the project, and the principle of operation of the system.
