Abstract:
In the electrical field, effective and dependable management and distribution of electrical power are crucial for maintaining a continuous electricity supply to consumers. With technological progress, Supervisory Control and Data Acquisition (SCADA) systems have emerged as an efficient method for real-time supervision and regulation of electrical distribution substation activities. In practical terms, cubicles are employed to oversee the electrical distribution network. A cubicle is a medium-voltage panel that serves the purpose of managing, gauging, and safeguarding the electrical distribution network. Integrating cubicles with the SCADA system is necessary to achieve real-time oversight and control of electrical substation activities. Developing a SCADA system necessitates simulation to offer an understanding of how the SCADA system can be merged and operated in an authentic environment at the distribution substation. The design process of a SCADA simulation for a 20 kV cubicle panel at a primary electrical distribution substation is the focus of this study. A dummy is utilized to represent the Circuit Breaker (CB) in the cubicle, serving the function of disconnecting and controlling the electrical network. Measurement of voltage, current, power, and network frequency is carried out using a power meter. The dummy is linked to a Remote Terminal Unit (RTU) as the controller, which in turn connects to the Master Terminal Unit (MTU) via a telecommunications network. At the MTU, a Human Machine Interface (HMI) is incorporated to control and monitor the status of the dummy. The monitoring and control system simulated SCADA has the capability to oversee and manage five simulated components and show measurements for power meter parameters such as voltage, current, power, and frequency.
