Analyzing Voltage Drop Disturbances in Photovoltaic-Powered Container Cranes: a Numerical-Based Approach

Solar energy is a promising sustainable option for powering vital infrastructure, such as cargo cranes at ports, aligning with Indonesia's goals for ecologically sustainable port development. Ensuring the reliability of electrical components, like crane motors, is crucial for smooth operations, requiring adequate voltage support. Voltage drop, a reduction in voltage when power is used, can affect performance. A detailed numerical analysis has been conducted to assess power distribution and voltage drop in crane components powered by photovoltaic (PV) sources. The study has found out that the voltage drop has remained within the permissible limits set by the International Electrotechnical Commission (IEC), with losses recorded at 1.61%, 0.17%, 0.43%, and 0.95% for motor hoists, gantry motors, boom motors, and trolley motors, respectively. These findings underscore the importance of continuous monitoring in order to ensure optimal performance and the longevity of electrical infrastructure in port operations.
