    • The invention is concerned with a device and a method for controlling an inverter associated with a power source, which typically will be a distributed power source. The role of an inverter is to modulate the electrical power output, e.g. to provide a three phase AC electrical output at suitable voltage, where the output is to be supplied to a conventional power distribution, grid. The invention involves modelling the behaviour of a synchronous electrical generator. Variables represent the angular position and rotational speed of the virtual rotor (14) of this virtual synchronous generator. The torque electromagnetically exerted on the rotor is calculated from a measured inverter output current, and from a variable representing excitation current in the rotor. Allowing for this and for a notional drive torque applied to the virtual rotor (which in the physical analogue would be supplied by some prime mover such as an engine), as well as for the virtual inertia of the rotor, the angular speed of the virtual rotor is calculated, Using the angular position and rotational speed of the virtual rotor, and allowing for the aforementioned excitation current, it is possible to obtain the cmf induced in stators of the virtual generator. On this basis a control signal is generated which causes the inverter to produce an AC output corresponding to that which would be provided by the virtual synchronous generator. A synchronous generator must be regulated, as too must the virtual synchronous generator of the present invention. To this end, the invention provides a feedback loop in which deviation of the rotational speed of the virtual generator rotor from a reference angular speed is detected and is used to adjust the virtual drive torque, thereby to regulate the rotational speed of the rotor and hence the frequency of the AC output and the real power supplied by it.

    • The garment parts hereof, namely the garment placket, collar and cuffs, have a smooth, neat appearance, obviating the need even for touch-up ironing, and thus are particularly suitable for wash-and-wear promotion. Moreover, the fabric for these parts, although not possessing "recoverable" stretch and thus heretofore unsuitable for my prior patented sewing technique for achieving pucker-free seams (U.S. Pat. No. 3,453,662), are now adapted to be sewn so as to provide the patented result noted. To a significant extent, this desired wash-and-wear performance is achieved by an artificially created "recoverable" stretch in the lining fabric. That is, the invention contemplates converting, by attachment of a control strip to said lining, what is ordinarily bias stretch of a non-recoverable nature therein into that of a recoverable nature, with the result that said "stretch recovery" relieves the sewing thread of tension and tautness and thus minimizes stitch pucker, wrinkles and the like from being manifested in the shirting fabric.In result therefore, the control strip solves a dilemma presented in the sewing of non-stretch fabrics. The dimensional stability of the non-stretch liner in the straight is required, yet it is unusable because it sews very badly. A bias interliner is also unusable because, while sewing well, it elongates under the stress of the sewing operation and thereafter shrinks back to the dimension of the non-stretch shirting being sewn together with it, causing pucker, bubbles, ripples and distortion after the sewing operation has been completed. The liner and control strip combination thus contemplated in this invention gives the dimensional stability of non-stretch coupled with the sewing qualities of stretch, all to the end of providing the favorable sewing result as set forth in my prior patent, U.S. Pat. No. 3,453,662.
