Dear Sirs,
I am having a little bit of difficulty understanding the datasheet, which is attached, for a 315kW BROOK Crompton Motor. Specifically, I could use some help understanding the significance of the current values. Is the 526.2 Amps (labeled Amps Ia @ 400V) the locked rotor current...
Dear Sirs,
I have an XLPE submarine cable with the following characteristics:
Cable Vn (kV) In(A) Rac(Ω/Km) L (mH/Km) C (μF/Km)
150 1088 0.0205 0.352 0.233
Using the parameters above can someone demonstrate how to calculate the reactive current in the cable in A/km and...
Dear All
I am building a simulation model using the Simpowersytems toolbox within Matlab Simulink. I would like to model a 20km XLPE underground cable using the distributed parameters cable model contained within Simpowersystems. The cable is 3 phase and contains three conductors in a trefoil...
Dear Sirs,
I was wondering if it would be possible to have a transformer with multiple primary windings that would allow two different voltages (lets say 11kV and 6.6kV) to be connected on the primary side. There would then be a single output on the secondary side of 33kV.
Presumably you...
Dear Sirs
I am trying to do a calculation relating to the connection of a 3.6 MW offshore wind-farm to shore via a 9km long subsea cable. The scenario is as follows and is taken from an example in a text book (page 236 Example 10.5 of the attached PDF):
A three phase XLPE subsea cable...
Hi All
I am using the embedded Matlab function block to write some code for a state machine. Within the block i have the following code:
function [AC_Contactor,DC_Contactor,AC_Precharge,DC_Precharge,X] = V_ctrl_AC(B1,DC_Voltage_Ref,DC_Link_Voltage)
AC_Contactor=0; DC_Contactor=0...
Dear Sirs
I am working with a Control Techniques Permanent Magnet AC Servo Motor. I am looking to feed the motor through a full bridge rectifier (Six Diodes) and would like to workout what the rectified DC voltage will be. On the data sheet the the Ke(voltage constant) is given as Ke = 98Volts...
Dear Sirs
I was wondering if anybody could provide me with some information on how to obtain the Torque Constant ,KT, of a small permanent magnet generator. The generator in question can be seen here http://dvetech.dk/?page=PMG&id=63. The part number is PMGO-0.2-200. I have also attached the...
