“…Such ripples in the results of the works [7,9,10,12,13] could be removed by the use of such exact-time averaging techniques. The difficulty with exact-time averaging within a fixed-frame-rate system is that the desired time period to average over is normally not an integral multiple of the frame time.…”

The architecture is designed to fulfil a number of emerging requirements pertinent to distributed generation and microgrid control applications: The measurements must settle quickly; within ~5 cycles for a frequency or voltage measurement used by a droop controller, and within ~2 cycles for an amplitude measurement used for protective relaying. The measurements must be able to track rapid frequency changes up to 10Hz/s during islanded operation. The measurement of frequency should be able to ride through single-phase, two-phase and partial-depth three-phase faults indefinitely. The frequency measurement should also be able to ride through a full-depth three-phase fault for a configurable amount of time. To enable deployment on cheap microcontrollers, the major signal processing algorithms should be able to operate at a fixed frame rate, possibly clocking as slowly as 10 samples per cycle (500Hz for a 50Hz power system; a frame time of should be better than ±0.01pu for 2-cycle measurements (protective relaying) and better than ±0.001pu for 5-cycle measurements used as inputs to reactive-power droop controllers.The simplest examples of algorithms for single-ph...

“…A useful concept is that of normalising the response such that the dynamics of the frequency measurement are unaffected by the amplitude of the input signal [12,13]. A useful foundation for the work presented in this paper is [14] which recognises the enormous value of averaging over exactly one single signal period using [15].…”

“…The PLL was originally described in 1923 and 1932 [4] and has been used as a common way of recovering and utilising phase and frequency information in electrical systems. In the area of power electronics, the PLL technique has been adopted in the speed control of electric motors, as well as synchronising of utility voltages and the control of currents or voltages in utility interface operations [5].…”

This paper describes the development of a new generation of power converter, used to power telecommunications equipment. A telecommunications converter must comply with the psophometric noise standard CCIF-1951 and the IEC1000-3-2 harmonic standard. While the IEC1000-3-2 standard is easily met with active power factor correction techniques, a high degree of effort is usually required to meet with the psophometric standard.Therefore, a control methodology utilising a three-phase phase-locked loop is introduced as a method of complying with the psophometric standard under distorted mains conditions. Simulations show that combining this with a novel feedback controller, results in an improved load step response over using a traditional proportional integral type controller.
