It is proposed to use filters with the minimal number of characteristic parameters, as a combination of Butterworth filters, as stabilizers in system-structural analogue of Tikhonov's regularization method.","PeriodicalId":184476,"journal":{"name":"2000 5th International Conference on Actual Problems of Electronic Instrument Engineering Proceedings.

Influence of high-frequency electrotechnological installations on generation of harmonics in a network 高频电工设备对电网谐波产生的影响

The coupling simulation of network and electrotechnological installations, for example, 400 kW/0.44 MHz, which can correspond, for example, to HF generator, is a very complicated task due to the large frequency ratio (more then 8000 times) between network and installation that leads to the significant increase of the calculation time. At the same time, coupling simulation gives full and exact information about harmonics generation in a network. But electromagnetic processes in the HF electrical part of the generator have steady-state values in the time range 40-100 /spl mu/s. Besides, the HF generator contains low frequency filter elements that prevent the HF harmonics (0.44 MHz and above) penetration in a network and permit to define the level of network harmonics with a good accuracy. The different frequency characteristics of the network-generator system, and their comparison with time-domain study, are overviewed.","PeriodicalId":184476,"journal":{"name":"2000 5th International Conference on Actual Problems of Electronic Instrument Engineering Proceedings.
