In the first course in Electrical Engineering, one is taught about the equivalence between star and delta winding and the formula for conversion from star impedance to delta impedance and vice versa. An impression is created that, looking from terminals, performances of star and delta windings are...

When you selectGet Data > From Webin Power Query Desktop, in most instances you'll enter URLs in the Basic setting. However, in some cases you may want to assemble a URL from its separate parts, set a timeout for the connection, or provide individualized URL header data. In this case...
When importing Excel data, you may notice that certain number values seem to change slightly when imported into Power Query. For example, if you select a cell containing 0.049 in Excel, this number is displayed in the formula bar as 0.049. But if you import the same cell into Power Query...
For multi-objective optimization, some improved QP methods have been introduced. Ref. [58] proposed a method for simultaneously optimizing the location and capacity of DGs in radial power distribution networks using a Mixed Integer Linear Programming (MIQP) approach. The optimization formula of the ...
You can also enable column binding in existing queries or in queries used in Power Query Online by manually adding theEnableColumnBindingoption to the connection in the Power Query formula bar or advanced editor. For example: Power Query M ...
The transformers have one secondary winding in a star connection and one in a delta connection. The outputs of rectifiers are connected to DC busbar through chokes Ld1 and Ld2, which not only smooth the output voltage ripples, but also serve to eliminate equalizing currents. These currents ...
Step 1:Calculate PPRACH, target power using following formula. preambleReceivedTargetPower is available by RRC parameter“preambleReceivedTargetPower” DELTA_PREAMBLEcan be obtained using prach-configuration Index translation to preamble format and then lookup in following table ...
(\Delta t\)represents the difference between hybrid power system output and load demand, the SMES power rating, the SMES energy storage capacity at period t, minimum and maximum energy storage limits, and the time interval (1 h). The state of charge (SOC) is an indicator of the energy ...
Run this DAX query to see the measure, description (if available — I added some for this example), DAX formula, and home table of all the measures in the model. Documenting your model just got a lot easier! Copy the results where you need with the Copy button. ...
