Determining the Optimal Location for Multi-Contact Switching Systems
Abstract
The paper highlights that integrating distributed power generation facilities into power supply systems for rural consumer with voltage up to 1000 volts leads to the challenges in managing the confguration of the associated electrical grids. To manage the configuration of power supply systems for rural consumers with voltage up to 1000 volts, it is proposed to use multicontact switching systems. However, there are currently no established methods or criteria for determining optimal locations for multi-contact switching systems in power supply systems for rural consumers with voltage up to 1000 volts that include distributed generation facilities. (Research purpose) The study aims to develop a method for determining the optimal placement of multicontact switching systems in rural electrical grids with voltage up to 1000 volts that include distributed generation facilities. (Materials and methods) An analysis is conducted to evaluate the implementation of configuration management devices in the examined power supply systems. The study explores the impact of installing multi-contact switching systems and identifies the main types of damage caused by power supply interruptions for agricultural consumers. Additionally, a method was developed to determine the optimal placement of multi-contact switching systems. (Results and discussion) The paper demonstrates the practical application of the developed methodology through a case study on the reconstruction of a rural electrical grid with distributed generation facilities. Among the proposed options, the optimal location for placing multi-contact switching systems was selected. (Conclusions) The installation of multi-contact switching systems helps mitigate damage from power interruptions for rural consumers. The choice of optimal locations for multi-contact switching systems is influenced by various factors, any of which can be decisive, depending on the specific circumstances. The developed methodology enables a comprehensive evaluation of all relevant factors, allowing for the most appropriate choice to maximize the overall efficiency of the power supply system. Using the proposed methodology to determine the optimal location for multi-contact switching systems results in a 55 percents damage reduction in the rural electrical grid caused by power outages.
