For some applications this form of data acquisition may be adequate. However , data recording applications that require large number of data readings where very frequent recordings are necessary must include instruments or microcontrollers to acquire and record data precisely (Rigby and Dalby, 1995). Laboratory Virtual Instrument Engineering Workbench (LabView?) is a powerful and flexible instrumentation and analysis software application tool which was developed in 1986 by the National Instruments (National Instruments, 2021). LabView? has bee a vital tool in today’s emerging technologies and widely adopted throughout academia, industry, and government laboratories as the standard for data acquisition, instrument control and analysis software. An existing kW rated windsolar hybrid power station is shown in Figure 1. The design and construction of the renewable energy based power system was reported earlier (Pecen, et al., 2021). The existing windsolar testbed at UNI campus has been an excellent educational opportunity for undergraduate and graduate students to study plex interactions in the electrical power grid between conventional coalfired power plants and windsolar based power stations. Particularly some ponents in the renewable energy plants such as batteries and dctoac power inverters can lead to power quality and grid stability problems when windsolar power systems are tied to fossilfuel based turbine and generators (Patel, 1999). These interactions are mostly due to the vast dynamics differences involved in wind turbines and steam turbines. Figure 1 shows four Photovoltaic (PV) solar panels with a power rating of 120 W for each, one mastmounted wind turbine with 1 kW, and an anemometer that includes a wind direction and a speed sensor. The hybrid windsolar power station operates in parallel, and charges a 12 V battery bank which includes six deep cycle lead acid batteries. The solar panels are installed on a frame which tracks the sun light during the day from an initial position of 0 degree to 320 degree. The system also includes a rated dctoac power inv
