Power frequency variation immunity test
1. Overview
This standard is the basic standard of EMC (Electromagnetic Compatibility), which involves the immunity test of electrical and/or electronic devices (equipment and systems) in their electromagnetic environment. Concerns only conducted phenomena, including the immunity of equipment connected to public and industrial networks.
This standard applies to electrical and/or electronic devices with a 50Hz three-phase power supply and a rated line current of each phase below 16A. Not suitable for electrical and/or electronic equipment connected to AC 400Hz distribution networks.
The purpose of the test is to study the effect of this disturbance on equipment sensitive to frequency variations of the power frequency. This effect is usually temporary.
Electrical and electronic equipment can be affected by changes in power frequency.
The AC line frequency from the utility system is directly related to the generator speed, as is the AC line frequency taken from an alternator not connected to the utility network. At any moment, the frequency depends on the dynamic balance between the load and the power of the power plant. Therefore, when this dynamic balance is changed, the frequency will change slightly. The magnitude and duration of the change depends on the nature of the load change and the plant's response to the load change.
Under normal circumstances, the frequency of the public system is announced by the power supply department with a nominal value (50 Hz) with a small bandwidth, and the frequency variation limit is within the bandwidth. In a non-interconnected system (isolated system), however, the variation in frequency may be larger and therefore more important.
Frequency changes affect:
Time-referenced control systems (measurement errors, loss of synchronization, etc.)
Equipment containing passive filters (detuned)
2. Test system layout:
Figure 1 shows the test configuration for the simulated power supply.
The test of the three-phase EUT is done by using a generator which is synchronized for each phase. For a three-phase system, the test shall be carried out on all three phases simultaneously, and the frequency variation shall be implemented on the three phases at the same time.
