High-voltage power supply systems in high-rise buildings are essential for ensuring safety, efficiency, and reliability. As living standards improve, the demand for stable and secure electrical infrastructure has increased significantly. The design of such systems must meet national standards and address the unique challenges posed by high-rise structures. Key objectives include ensuring high reliability, economic efficiency, and scientific design while meeting the diverse load requirements of building users. Additionally, power distribution must be optimized to manage capacity coefficients during different load periods, and high-voltage lines should be buried underground to maintain aesthetics and safety. For buildings with fewer than 30 floors, the power distribution room is typically located in the basement, which also houses facilities like garages, fire protection systems, and water pressure equipment. In taller buildings or those with higher floor counts, the transformer substation should be placed at the center of the load area, using a tree-like distribution layout. If the substation is in a mixed-use basement, special attention must be given to waterproofing, moisture control, ventilation, and minimizing power loss. Transformer selection and operation mode (single large unit or multiple smaller units) should be optimized for economic performance. A time-division parallel operation mode with computerized automation can help achieve efficient energy use across different time periods. Emergency generators are crucial for maintaining power during outages, especially in commercial high-rises. Their placement should be on ground level, considering factors like exhaust management, noise reduction, and ease of maintenance. Generators should be as close as possible to the transformer room for efficient wiring and management. In very tall buildings, multiple generators may be required depending on the power needs and system layout. Low-voltage power distribution design involves careful planning of transformers, junction operations, and load distribution. When a transformer fails, it's important to have strategies in place for load redistribution, including handling both general and critical loads. Seasonal variations in electricity usage—such as lighting, power, and air conditioning—must also be considered to ensure consistent service. Calculating electrical load in high-rise buildings is complex due to the unpredictable nature of residential usage. Factors like appliance choices, user behavior, and geographic location all influence consumption patterns. While some loads can be accurately calculated, others require estimation based on industry standards and designer experience. Recent data suggests an average household consumes around 5 kW, with long-term expectations of up to 10 kW. The low-voltage trunk line from the distribution room to the electrical shaft plays a vital role in the overall system. The design must consider the type of busbars or insulated conductors used, as well as the connection between main and branch lines. Ensuring reliability and ease of installation is key to avoiding long-term operational issues. Weak current system design focuses on modern, intelligent, and networked solutions. It requires thorough planning, including user needs analysis, feasibility studies, and implementation strategies. The goal is to create a reliable, scalable, and user-friendly system that meets both technical and economic constraints. The electrical shaft design is crucial for housing critical components like prefabricated branch cables, which offer better protection, seismic resistance, and cost-effectiveness compared to traditional methods. The shaft’s location and size should align with the building’s layout and electrical needs, while also accounting for future expansion and maintenance access. Finally, metering systems should be designed to be centralized and accessible, ideally placed outdoors to prevent disturbances and facilitate management. For multi-story buildings, a modular approach—such as grouping every 10 floors—can simplify installation and reduce costs. Remote monitoring and control systems enable efficient and modern management practices.
