Large data centers require uninterrupted power supply to ensure continuous operation, and backup generator sets are an important part of ensuring uninterrupted power supply. Therefore, backup generator sets need to use such load detection equipment for regular loading and maintenance to prevent serious losses caused by unexpected power supply situations.
Sunwin Data Center Generator High Voltage Load Bank can test the output power and load capacity of data center backup generator sets, and perform sudden loading and unloading tests to understand their performance status and establish a physical examination report for them. Accurately measure the basic functions such as steady-state three-phase voltage, current, active power, frequency, and running time of the generator; voltage and frequency setting test, fluctuation test, and transient test functions, which can automatically test the maximum and minimum voltage, maximum and minimum current, maximum and minimum frequency, and recovery time when the load changes suddenly; and has a powerful voltage recording function, which can not only call for all steady-state parameters, but also call for sudden addition, sudden unloading, voltage, current, frequency curves, and voltage, current harmonic curves and harmonic content, and cooperate with the host computer to automatically complete the measurement of all electrical parameters and dynamic parameters of the generator. - 2025-03-26Application of Sunwin generator load bank in photovoltaic power generation systemPhotovoltaic power generation system is a new energy system that uses solar energy to generate electricity, and the generator load bank is an important part of the photovoltaic power generation system. The generator load bank can achieve reactive power compensation by adjusting the current phase and voltage amplitude, thereby improving the efficiency and reliability of the photovoltaic power generation system.
In the photovoltaic power generation system, due to the instability of solar energy and the influence of weather, the output voltage and current of the photovoltaic battery group will fluctuate, thereby affecting the efficiency and reliability of the photovoltaic power generation system. The generator load bank can achieve reactive power compensation by adjusting the current phase and voltage amplitude, thereby eliminating the reactive current in the power system and improving the efficiency and stability of the photovoltaic power generation system.
The application of the generator load bank in the photovoltaic power generation system mainly includes the following aspects: - 2025-03-24In-depth analysis of load bank technology: an advanced journey from basic principles to intelligent control• Load simulation principle: The load bank mainly tests the performance of power supply equipment by simulating various actual loads. Its core is to use components such as resistors, inductors, capacitors, etc. to form different types of loads. For example, resistive loads are used to simulate purely resistive electrical equipment, such as electric heaters, etc., and the load size is adjusted by changing the resistance value; inductive loads can simulate devices with inductive characteristics such as motors, which will cause the current to lag behind the voltage; capacitive loads are similar to some electronic devices with capacitive characteristics, and the current will lead the voltage. By combining these different types of load components, various complex actual load conditions can be simulated.
• Power consumption and heat dissipation principle: The load bank consumes a lot of electrical energy when working, which is converted into heat energy. In order to ensure that the load bank can work normally and not be damaged due to overheating, a good heat dissipation mechanism is required. Common heat dissipation methods include natural heat dissipation, forced air cooling and water cooling. Natural heat dissipation relies on the device's own heat dissipation structure to dissipate heat into the surrounding environment, which is suitable for load banks with lower power; forced air cooling is to install a fan to accelerate air flow to remove heat, which is a common heat dissipation method for medium-power load banks; water cooling uses circulating water to cool the load bank, which has good heat dissipation effect and is suitable for high-power load banks. - 2025-05-28Application of load banks in shipyardsIn shipyards, the application of load banks runs through multiple links of ship power system construction and testing, which is crucial to ensure the safe and stable operation of ships, which is specifically reflected in the following aspects:
