Abstract—
A test facility for monitoring the performance of
the wind power system is presented in this paper. Based on the
LabVIEW software and the NI data acquisition card, theproposed system has the functions of data acquisition, data storage and signal analysis of the wind power system. Thisentire system involves the integration of a personal computer,data acquisition card and relative conditioning circuits. It isproved by experimental results that it can effectively reflect thereal function state of the system. The proposed system permitsthe rapid system development and has the advantage offlexibility in case of changes; it can also be extended to controlthe wind power system.
I. INTRODUCTION
LONG with the rapid development of renewable
energy technology, a significant amount of wind power
systems were installed during the last two decades. To
better evaluate and optimize the performance of such a
system, it is necessary to get detailed information of the
meteorological and electrical parameters [1, 2, and 3]. This
test system proposed is designed to collect and store such data
as well as monitor its real time performance, using LabVIEW
software. The data acquisition (DAQ) of LabVIEW can
measure a wide variety of signals while in this proposed
system, voltage, current and wind velocity is collected. In
order to evaluate the quality of the power generated by wind
turbines, the signal analysis function is also designed to
execute the Fourier transform and the autocorrelation
function. Sensors are used to transfer other kinds of signals
(like wind velocity) to the signal of voltage while the
conditioning circuits are used to force the voltage signal at a
definite range that is suitable for the data acquisition card to
collect. The sensors used in this system contain the voltage
transformer, the current transformer and the anemograph. The
voltage transform is used to measure the lone voltage of the
wind turbine and the current voltage is designed to measure
the output DC current that flows out of the rectifier.
Anemograph should be waterproof and voltage-output which
is easy for the data acquisition card to collect. Fig. 1 points
out the hardware
architecture of the data acquisition system.
