Abstract
Solar array fed water pumping system is a good approach for water management and agriculture purpose. PV panels highly depend on unpredictable environmental conditions, as a result, the development of a PV system is with more technical challenges. System-level simulation on a desktop computer has limitations, such as uncertain accuracy of the models, unable to test the system realtime behaviour and the communication and measurement of sensors that are required on physically implementing the system. On the other hand, implementing tests for a physical system has defects like high cost, unsafety and long development cycle. Therefore, based on the OPAL-RT real-time simulation platform OP4510, this project has implemented the real-time hardware-in-loop (HIL) simulation of the solar array fed water pumping system. In the meanwhile, the proposed HIL emulation system provides a virtual testing environment in the ESP Lab for solar panels, batteries or electrical machines.
