Exercise: Designing a Bulk Substation

Scenario: You are tasked with designing a new bulk substation to serve a growing community. Consider the following factors and outline a basic plan for your design.

Factors:

• Location: Choose a location with good access to the existing transmission line and suitable land for the substation.
• Power Capacity: Determine the required power capacity based on the projected demand of the community.
• Voltage Levels: Consider the voltage level of the transmission line and the desired distribution voltage for the local area.
• Safety and Protection: Implement appropriate safety measures and protective relaying systems to ensure the safe operation of the substation.
• Monitoring and Control: Include modern monitoring and control systems for real-time data analysis and operational efficiency.

Your Task:

• Draw a simple diagram of your proposed bulk substation layout.
• Identify the key equipment (transformers, circuit breakers, control systems, etc.) and their placement within the substation.
• Briefly describe the main functions of each component and how they contribute to the overall operation of the substation.
