Design and Development of Testing Devices for Photovoltaic/wind Power Grid Connection
This paper analyzes the grid code requirements on wind power/photovoltaic grid connection in domestic and then introduces their characteristics of low voltage ride through(LVRT)
grid adaptability and testing devices. According to the current standard system
a LVRT and a grid adaptability testing device are developed respectively. Working principle and features have been introduced in this paper
meanwhile
the devices have been applied in a photovoltaic power station and the features have been verified. The test results show that:the two devices are convenient
reliable
which are independently tested
and can fully meet all technical specifications and functional requirements relevant to wind power/photovoltaic grid connection.
