Synchronous Generator Integrated with PV Array System

In solar power generation systems, the synchronous generator serves as a critical component that operates in coordination with the photovoltaic (PV) array to convert solar energy into electrical power. The synchronous generator is an AC generator whose rotational speed synchronizes with the frequency of the power system. It generates electricity at a fixed frequency, which is essential for maintaining grid stability and power quality. From an implementation perspective, the system typically requires maximum power point tracking (MPPT) algorithms to optimize PV array output and synchronization control logic to maintain phase alignment with the grid. Key functions include voltage regulation using automatic voltage regulators (AVRs) and frequency stabilization through governor control systems. The integration often involves power electronic converters with PWM control strategies to interface the DC output from PV arrays with the AC synchronous generator. Therefore, when selecting solar power generation systems, special attention must be paid to the performance and quality of the synchronous generator, particularly its efficiency characteristics, fault ride-through capabilities, and harmonic distortion performance. The control system should implement robust algorithms for grid synchronization and power management to ensure reliable operation under varying solar conditions.
