Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/104882
Kind Code:
A1
Abstract:
In a large-scale system including a plurality of photovoltaic power generation systems, since curve tracers are built in respective power conditioners, it is impossible to manage and control the respective curve tracers in synchronization with each other and therefore it has been difficult to make an evaluation by comparing the outputs under the same power generation condition.
The photovoltaic power generation systems have solar radiation intensity detectors (311, …, 3N1) that can detect the solar radiation intensity of photovoltaic arrays (41, …, 4N). In the photovoltaic power generation systems, the DC voltage detection values (V) and DC current detection values (I) output from the respective photovoltaic arrays (41, …, 4N) are input through communication devices to a remote monitoring control device (1) having a curve tracer device (11) with a display while the DC voltage detection values (V) and DC current detection values (I) corresponding to the respective photovoltaic arrays (41, …, 4N) are synchronized with each other. The I-V curves and solar radiation intensity curves based on the solar radiation intensity values detected by the solar radiation intensity detectors (311, …, 3N1) are then created by the curve tracer device (11) and the created curves are displayed by the display.
