A Control of SynRM using MPPT Algorithm and Effects of Advance Angle on Motor Performance

Abstract

Solar-powered irrigation systems are quite important in terms of renewable energy usage. These systems consist of solar panel, boost converter, battery, battery charge management system, motor drive, motor and pump. The installation costs of system increase and the system reliability reduces due to the amount of equipment. Nowadays, low-voltage Permanent Magnet Synchronous Motors (PMSMs) are used to eliminate drawbacks of the boost converter. However, PMSMs have high cost because of the magnets. Synchronous Reluctance Motors (SynRMs) having lower cost than PMSMs can be used in these applications. The proposed system can be operated by using only the solar-panel, SynRM and drive without other devices. Thus, the system cost can be significantly reduced. In addition, durability of the system can be increased due to not using battery and magnets causing problems such as maintenance and low lifespan. A SynRM pump motor which can operate with a lower voltage level generated by the photovoltaic (PV) panel was designed in this paper. This motor has high efficiency because of no-copper losses of the rotor. Effects of advance angle on designed motor performance were analyzed and suitable advance angle was selected for the motor. Additionally, the designed SynRM was controlled by the MPPT algorithm.
