USING A SIMULATION MODEL TO DETERMINE THE ENERGY CHARACTERISTIC OF AN ELECTRIC RESISTANCE FURNACE COMPLEX AND A THYRISTOR VOLTAGE REGULATOR WITH A PHASE-PULSE CONTROL
The energy characteristics of the temperature controller of an electric resistance furnace that receives power from the AC network using a thyristor voltage regulator with phase-pulse control are considered. The research is carried out in relation to a complex that includes the resistance furnace itself, a thyristor voltage regulator with phase-pulse control, a temperature sensor and a regulating device that generates a proportional-integral-differential control law. In contrast to traditional research, the article analyzes the totality of electrical and thermal processes occurring in a complex of equipment that includes an electric resistance furnace and a thyristor voltage regulator with phase-pulse control. Using the developed simulation model, such virtual energy characteristics as total, active and reactive power, as well as the power factor that determines the efficiency of the complex and the installed power of thyristor voltage regulators are calculated. The influence on the efficiency of the complex of such an indicator as the excess of the installed power of the voltage regulator over the average power consumed by the furnace is analyzed.
