Project Case: Southern Power Grid Smart Grid Upgrade Project

Project Overview

• Project Name: Southern Power Grid Smart Grid Upgrade Project

• Location: Guangzhou City, Guangdong Province, China

• Total Investment: 150 million RMB

• Completion Date: September 2023

Project Background

With rapid urbanization, Guangzhou City faces a growing electricity demand. To enhance the reliability and intelligence of the power supply, Southern Power Grid Company decided to undertake a comprehensive upgrade of the existing grid, building a smart grid system to improve the safety and efficiency of electricity delivery.

Applications of Electrical Hardware

1. Substation Equipment:

• High-strength bolts and nuts are used extensively to secure transformers, switches, and other equipment in the substations, ensuring stability and safety.

• All connection points utilize locking nuts to prevent loosening due to vibration or temperature changes.

2. Cable Supports and Conduits:

• The project includes the installation of multiple cable supports made of galvanized steel, fixed with high-strength bolts to ensure safe and tidy cable management.

• All conduit connections use bolts and fittings to ensure sealing and structural strength.

3. Distribution Boxes and Control Cabinets:

• Stainless steel bolts are used to secure distribution boxes and control cabinets, enhancing corrosion resistance.

• Each connection point in the distribution boxes undergoes strict quality testing to ensure safety and reliability.

4. Monitoring System Installation:

• The monitoring system equipment for the smart grid is secured using specialized brackets, with high-strength bolts ensuring stability during operation.

• Cable management for the monitoring system is organized through cable trays and supports to maintain a neat appearance and avoid interference.

Quality Control

• All electrical hardware materials undergo rigorous quality inspections upon procurement to ensure compliance with national standards and industry regulations.

• Throughout the construction process, the project team conducts regular site inspections to ensure installation quality and safety.

Project Outcomes

• On-time Delivery: The project was completed on schedule in September 2023 and has commenced operations.

• Power Supply Reliability: The construction of the smart grid significantly enhances the reliability and safety of electricity supply, reducing the occurrence of power outages.

• Energy Efficiency and Emission Reduction: The new system improves operational efficiency, with an estimated annual reduction of approximately 500 tons of carbon emissions, supporting sustainable development goals.

Summary

The successful implementation of the Southern Power Grid Smart Grid Upgrade Project demonstrates the critical role of electrical hardware in power infrastructure. Through careful design and rigorous construction practices, the project ensures the safety and reliability of equipment, providing valuable experience for future power projects. This project not only enhances the electricity supply capacity of the city but also contributes positively to environmental protection.
