Simultaneously, the proposed SVG can generate the compensating current that prevents the reactive current from flowing into the grid.
When the VG generating the reactive current starts running, the SVG generating the compensating current also starts running right away and generates the corresponding compensating current to compensate the reactive current.
Besides, it is impossible to compensate the uncontrolled reduction of compensating current at voltage reduction on CB lower than the preset one in such a way.
At the same time, voltage deviations on CB bring distortions in the AFCD compensating current, reducing the provided power quality parameter [1, 2].
In this paper, the application of a fuzzy logic controller and adaptive neuro fuzzy inference system based on adding a compensating current signal to the switched reluctance motor to minimize the torque ripples is investigated.
To attenuate the torque ripple, the addition of a compensating current signal is proposed, as shown in Figure 1.
c]) as input, produces PWM switching signals through a hysteresis comparator device, accordingly regulates the compensating current
3rd step is to generate the reference compensating current
by using an IGBT based voltage source inverter as shown in fig 6.
The temperature compensating current
regulator, shown in Figure 3, has a temperature coefficient of 23 [mu]A/[degrees] C for noise source temperature compensation applications.
At this time, the active filter must provide the following compensating current
This phenomenon is justifiable since the negative sequence components of load reactive currents are also compensated by the APF, resulting in a higher compensating current
across the link-BC and link-CA.
An optimal control method entitled ant colony PI controller for extracting the reference compensating currents
to shunt active power filter under balanced voltage conditions, which is applied to eliminate line current harmonics and compensate reactive power .
