Abstract

This paper proposes a PV-based off-grid valve drive system for leakage protection in water networks. The system integrates photovoltaic panels, energy storage units, and motorized valve control mechanisms to ensure reliable and efficient operation. The PV panels harvest solar energy, which is stored for use during low-light conditions or at night. A motorized valve control mechanism driven by the stored energy actively manages valve opening and closing based on leakage detection sensor measurements. Moreover, maximum power point tracking (MPPT) for the PV panels is set to maximize the system efficiency. Then, power management is designed to control the power flow between the different system units and keep the valve actuator voltage constant under different operation conditions. Simulation results demonstrate the system's effectiveness in detecting and isolating leakage, reducing water loss, and minimizing system downtime. Furthermore, the system's off-grid nature enhances resilience against power disruptions, making it a sustainable solution for leakage protection in water networks.
