The construction plan for power collection system of a centralized solar project usually includes the following steps:
1. Design planning: Before starting construction, detailed design planning is required. This includes determining the layout of the power collection system, line length, transmission capacity, and cable selection. The design should also consider factors such as the safe distance, protective measures, and terrain of the power lines.
2. Material procurement: According to the design plan, purchase the required cables, poles, insulators, joints, and other related materials. Ensure the procurement of materials that meet quality standards and are suitable for specific project requirements.
3. Foundation construction: Carry out the construction work of the line pole foundation. This may involve excavating foundation holes, pouring concrete, installing wire rods and insulator bases, etc. Ensure the stability of the foundation and compliance with design requirements.
4. Cable installation: install the cable along the predetermined route. This includes buried cable, like Medium voltage power cable, Low voltage DC cable and solar cable, control cable, instrumentation cable and Overhead power line, like overhead conductor, OPGW cable, ADSS cable and fiber optical cable etc. depending on project requirements and environmental conditions. Ensure proper installation, protection, and grounding of cables.
5. Connection and insulator installation: After the cable laying is completed, the cable connection and insulator installation are carried out. This includes the installation of joints, fixing of insulators, and installation of protective devices. Ensure connection reliability and line safety.
6. Commissioning and testing: After the installation of the whole power system for a solar project, the commissioning and Test effort shall be carried out. This includes checking connections, grounding, and insulation to ensure the normal operation and safety of the line.
7. Operation and maintenance: Once the construction of the power collection system is completed, regular operation and maintenance work needs to be carried out. This includes line inspection, troubleshooting, insulator cleaning, grounding inspection, etc. to ensure the reliability and stable operation of the line.
Meanwhile, Please note that the construction plan for power collection system of a centralized solar project may be varied depending on the specific project requirements and local regulations. Therefore, in the actual construction process, it is necessary to carry out detailed planning and design according to the specific requirements of the project, and comply with local safety standards and regulations.
