Bài giảng Cung cấp điện - Chương 3: Xác định phụ tải điện

Chapter 3 of the Power Supply Lecture: Determining Load Calculation provides readers with knowledge about common concepts, load diagrams, relevant quantities, and calculation methods, load calculation according to IEC, calculation steps at each level of the power system, determining load center, load forecasting. This chapter focuses specifically on the concept of load, including general concepts, load diagrams, and related parameters.

Engineers, researchers in the field of electrical engineering, power system operators, and students studying power systems.

This chapter focuses on the concept of load in electrical systems, covering common terms, load diagrams, and relevant quantities. A load diagram represents the relationship between load power over time and characterizes the power demand of each device, group of devices, distribution system, or factory. Load calculation is dependent on various factors such as power and number of machines, operating modes of these machines, manufacturing process technology, machine operator skill level... Accurately determining load calculation is a challenging but crucial task. This chapter also introduces various load calculation methods, including short-term and long-term load forecasting. Short-term load forecasting refers to the prediction of immediate load for an operational power plant. This predicted load is often referred to as calculated load. In summary, this chapter provides readers with knowledge about common concepts, load diagrams, relevant quantities, load calculation methods, and load forecasting.
