“…If such analyzes have been attempted, they have involved dedicated solid-state protective relays [9,10] or relatively large EM devices, such as electromagnetic contactors [11,12]. In sporadic cases, limited simulation analyses of the operation of switches were performed [13]. This may be due to the problematic design of the measurement stand that would have to be built to analyze the operation of the relays.…”

The article incorporates an analysis of the switching-on process of alternating current (AC), low-voltage (LV), and electromagnetic (EM) relays energized by harmonically polluted voltage sources. In the undertaken research, the dynamic parameters of relays actuated by electromagnetic drive were examined for shape and supply voltage waveform distortion levels as described by different THD factor values. During the research, diverse supplying voltages were delivered to drive electromagnet coils at a variety of phases so as to reflect the stochastic nature of the energizing procedure. The performed analysis allowed for determining the most influential and decisive factors dictating the basic parameter values of the switching-on process. As an outcome, time-related parameters of relay moving armature movement were obtained, and the frequency of disorder occurrences during the switching-on was examined. For experimentation needs, an experiment stand was developed, and dedicated software for measurement results analysis was elaborated. Based on the study results, EM relay switching-on operation reliability was evaluated in view of electric energy quality.

Dynamic characteristics reflect the real situation of an AC contactor and are very important to the optimum design of AC contactors. A simulation model of intelligent AC contactor has been established using the ADAMS software with developing a user subroutine in which the iterated Runge-Kutta method is adopt to solve a set of differential equations that describe the coupling of circuit, electromagnetic and mechanical systems. Because of reusing the analysis results obtained from the simulation of static characteristics accomplished by the ANSYS software, the simulation model runs more efficiently. In addition, by using the ADAMS/solver in the batch mode, an optimization library have been integrated with the ADAMS software and successfully used to seek the optimal control parameters to minimize the contact bounces and core bounces. The simulation results show that the intelligent AC contactor with PWM control can effectively reduce the bounces and energy consumption.
