High-power AC load bank is a device used for simulating and absorbing AC electrical energy. By adjusting parameters such as its own resistance, inductance, and capacitance, it can simulate various load conditions of different natures and sizes. It plays a crucial role in multiple fields and has a wide and diverse application range.

In the field of power electronics testing, rack-mounted load bank, with its standardized design and flexible deployment capabilities, is widely used in laboratory research and development, quality inspection on production lines, and on-site operation and maintenance. However, the performance requirements for it vary significantly in different scenarios. Reasonable selection is the key to ensuring the test efficiency and data reliability.

Traditional fixed-specification dummy loads often struggle to meet diverse testing requirements. The modular dummy load, designed with standardized interfaces and pluggable units, decomposes testing capabilities into independent modules for power, impedance, and waveform simulation.

In the field of industrial testing and power systems, intelligent load banks are undergoing a revolutionary transformation from traditional analog devices to digital smart terminals. With the deep integration of artificial intelligence (AI) algorithms and Internet of Things (IoT) technology, load banks are no longer limited to simple load simulation but have evolved into core infrastructure with autonomous decision-making, remote collaboration, and data-driven capabilities.

In the field of modern industrial testing, Load bank is an indispensable cornerstone, providing key support for the performance evaluation of all types of power electronic equipment. From the battery management system of new energy vehicles to the power supply network of data centers, Load bank is an important tool for verifying the reliability and stability of equipment with its excellent ability to simulate real loads.

In the field of industrial testing, load banks serve as precision power equipment whose performance stability directly impacts the accuracy of test data and the reliability of tested devices. However, many users often overlook maintenance and calibration, leading to premature equipment aging and increased failure rates.

In the field of industrial equipment testing, load banks—a core tool for simulating real operating conditions—play a critical role in determining testing efficiency, equipment reliability validation, and R&D cycles. Given the complexity of industrial scenarios and diverse testing requirements, selecting the right load bank has become a pivotal challenge for engineers and technical decision-makers.

Driven by the "double carbon" goal, energy storage technology has become the core carrier of the energy revolution. From electric vehicle batteries to grid-level energy storage plants, the performance verification of energy storage systems relies on efficient and accurate testing methods.

In power system test, the selection of load bank directly affects the test efficiency, data accuracy and equipment safety. In the face of diverse application scenarios, it is necessary to consider from multiple aspects such as technical parameters, functional requirements, and environmental conditions.

In the modern power system, the load bank, as the key test equipment, undertakes the important mission of ensuring the safe and stable operation of the power grid. From the power generation side to the power side, from traditional thermal power to new energy grid connection, the load bank provides indispensable technical support for the performance verification of power equipment and the stability analysis of the power grid by simulating the real load and fault scenario. This paper will deeply discuss the core value of load bank in power system, and analyze its application practice in stability testing and fault simulation with specific cases.
