Abstract


Analysis of past and existing off-grid wind power generation system , a variety of test systems , wind power system testing involves parameters more complex type of expensive testing process in time domain parameters requires strict counterpoint to the traditional general-purpose instrument not only price and poor coordination among instruments , it is difficult if not impossible to meet the testing requirements . Developed a new type of intelligent LabVIEW-based virtual instruments off-grid wind generator performance test system to resolve the above problems . The subjects completed the design and assembly of the experimental program of indoor and outdoor hardware performance test systems, off-grid wind turbine ; selected off grid wind turbine generator units the test real test standard sensors , transmitters and DAQcard 6024E multifunction data acquisition card, and a combination ; achieve the automatic data acquisition , recording, processing, and storage functions . Off grid wind generator performance virtual test system can test the wind generator output current , output voltage , frequency , ambient temperature, ambient air pressure , on-site wind speed , generator torque signal , at the same time by the above experimental data for real-time collection , analysis and processing to obtain the characteristic curve of a wind power generator output . The test data can be read immediately through the computer , and stored in the computer at the same time . Also facilitates instantaneous and average values ??of the parameters ; guarantee the instantaneous value of the various parameters in the time domain strictly -bit multi-parameter manual testing methods can not solve the problem completely solved , and Excel software obtained indoor , outdoor experimental data processing and mapping , you can get the speed - power wind speed - power \These to reflect the curve of the characteristics of the input and output of the wind turbine , off-grid wind turbines may be correct , objective assessment of the basic technical indicators , but also for the improvement , development of off-grid wind generators provide a reliable basis . Through field testing , and the experimental data analysis and processing to obtain satisfactory results , with the performance of real-time , stability and accuracy of the wind power test system , fully able to meet the design study of the off-grid wind turbine blades improve research needs and generators .
