一种计及低电压穿越的有源配电网继电保护方案
A Relay Protection Scheme of Active Distribution Network with LVRT
According to the real situation of lack of monitoring device for stand-alone PV power plant in rural areas of China, this paper introduce a data monitoring system which based on embedded platform. This system adopts modularization design which includes signal collecting, DSP signal processing and ARM processing platform. The accuracy of data counting is apparently improved because the data collecting unit adopts 16 channels synchronous sampling; system can collects, counts, displays and stores plant operation data for system analysis effectively, since combination of DSP and ARM. This solution is useful to design monitoring system which will be more portable, lower cost and energy consumption.
