Increasing the Power of Electric Arc Furnace Using Compensating Devices

A.A. Nikolaev, G.P. Kornilov, V.V. Anokhin

Abstract


The article discusses methods of reactive power compensation low and ultra-high power electric arc furnaces. The results of using compensating device are shown by the example of EAF-10. The formula is given to calculate the reactive power of capacitor banks of the second harmonic filter. Also, the operation mode of thyristor controlled reactor is considered which reduce the EAF active power losses. Also, this article describes a new connection circuit of SVC at power supply system of ultra-high power EAF and the advanced algorithm that maximizes the power of EAF.

The issues discussed in the article relate to units that include EAFs of different capacities. The new connection circuit of unit EAF-SVC can be used only when reactor and furnace transformer are separate devices.
