Abstract
Ensuring an uninterrupted power supply is essential for industrial, commercial, and residential users. One effective method to achieve this is by implementing asymmetrical operation on transmission lines. This study introduces a power compensation strategy designed to maintain a continuous power supply, even during permanent single-phase faults on the transmission line. The proposed method leverages the compensating properties of the IPC 240 and the hybrid wind-photovoltaic technologies. The study focused on a 3 MW, 30 kV transmission line equipped with dual three-branch Interphase Power Controllers 240, which experienced a 33 % power loss due to a permanent single-phase fault. A hybrid wind-photovoltaic system, supplemented with battery storage, was modeled and sized to compensate for the power loss and integrated into the line. The power management strategy operates in two main modes. In mode 1, the line operates without faults. In mode 2, when a permanent single-phase fault occurred, the transmitted power dropped to 2 MW, necessitating the integration of the hybrid energy source to compensate for the reduced power. Weather fluctuations are factored in the management strategy, guaranteeing a stable power supply from the hybrid energy source. Simulations conducted using MATLAB/Simulink demonstrated the system's capability to maintain an uninterrupted power supply to the load. Even under permanent single-phase fault conditions and adverse weather, the system restored power to nearly 2.96 MW, achieving a 99 % compensation rate, which is the highest compared to previous studies.
