【正文】 erter based on solidstate devices, protection equipment such as ac and dc circuit breakers, fuses, surge arrester, a set of linear and nonlinear loads, connecting cables, and junction boxes. Students are introduced to the studies of steady state voltage and currents in the system, illustrating power quality problems due to small linear and nonlinear load effects (Pecen and Timmerman, 1999). The windsolar hybrid power station has been used as part of the undergraduate electrical power and machinery laboratory content as well as a demonstration unit for visiting high school and munity college students (Pecen, et al., 2021). 6 Although the power system and renewable energy content of the project have helped in teaching realworld applications of the renewable energy, the lack of puter aided instrumentation and data acquisition modules prevented us from developing a stateoftheart data monitoring and processing system in 1999. This paper will focus mainly on recently pleted LabView? based data acquisition module for monitoring and processing the following system state variables: dc voltage, dc current, ac voltage, ac current, wind speed, wind direction, dc power, and ac power from the existing windsolar power station. The instrumentation system provides students with an opportunity to gain practical experience on National Instruments (NI) data acquisition hardware, and the LabView? Version 6i software for the realtime monitoring of dc voltage, dc current, wind speed, wind direction, dc and ac power waveforms. Other most useful benefits of the project include the students’ ability to interface devices such as voltage and current sensors on both ac and dc sides, and the use of isolation amplifiers between sensor outputs and puter inputs. The developed system has not only been used for data acquisition and instrument control applications, but also for general purpose applications such as database development, data analysis programs, and work munications. For example, the puter executing the realtime virtual instrumentation of the windsolar power system is worked to the university server, and can be accessed by any remote puter on campus through the work for realtime monitoring purposes. An alumni survey covering last 15 year of graduates was pleted in summer 2021 in the Department of Industrial Technology at UNI. The survey instrument was sent to 120 alumni who are invo
