Title: Device for checking ac drives for operation at transients
Inventor: PARSHINTSEVA A N
IPC: H02P6/16
Filed: 2002-08-13
Granted: 2004-02-27
Abstract: FIELD: measuring synchronous-machine instant error angles Θ and induction- machine slip and torque under steady state and transient conditions. SUBSTANCE: device has electric (raster and reference) pulse shapers built around raster disk mounted on electrical machine shaft, these shapers affording high-precision recording of instant position of revolving shaft. Instant positions of magnetic flux of both synchronous and induction machines are recorded by means of supply mains reference pulse and magnetic flux position pulse shapers. Supply mains reference pulses are shaped at instants when supply voltage crosses zero. In the process length of present voltage half- cycle (time length between two supply mains reference pulses) is continuously measured. For measuring instant values of synchronous-machine angle Θ relative positions of instant flux position pulses and raster pulses recorded during calibration (under no-load conditions when Θ = 0) and when any pulse is shaped under any operating conditions are compared. Slip measurements are made by continuous comparison of time intervals within which K last magnetic flux position pulses of induction machine and K last raster pulses are shaped. Amount of slip and its polarity are found from equation   where t       (K)   m.p.        and t       (K)   t        are measured time intervals of shaping K magnetic flux position pulses and K raster pulses last at the moment. Θ or s measurements can be made at rate of shaping magnetic flux position pulses of machines or at any desired intervals. EFFECT: enhanced precision of determining shaft torque of respective machine. 5 cl, 1 tbl
