Title: Controlling operation of continuous arc furnace comprises controlling current and voltage of arc via rectifier and movable electrode
Inventor: PEZET FRANCOIS
IPC: H05B7/148
Filed: 2001-06-01
Abstract: In addition a real operating characteristic of the rectifier (7) is determined and as a function of this characteristic and of the reference value of the current (Iref), an optimized current (Iopt) is determined to avoid saturation of the rectifier. This optimized current is then used by the means of controlling the rectifier.  The furnace (1) has a movable electrode (4) and at least one floor electrode (3) supplied via at least one rectifier. The arc voltage (Uarc) is controlled by means (10) of moving the position of the movable electrode, and the arc current (I) is kept constant by means (25) of controlling the rectifier, to keep the voltage and current at a reference voltage (Uref) and current (Iref) during operation of the furnace. The optimized current (Iopt) is less than or equal to the reference current (Iref), preferably between 90 and 100% of the reference current. If the characteristic function of the rectifier indicates that it is close to saturation, the optimized current is chosen to be less than the reference current, but if it is far from saturation, the optimized current is chosen to be the same as the reference current. The rectifier contains thyristors with a variable retarding angle ( alpha ) and the current is controlled by varying the retarding angle between a lower ( alpha inf) and upper ( alpha sup) value. The real value of the retarding angle ( alpha reel) is determined as the characteristic of the rectifier and compared to a limit angle ( alpha lim). If the real angle is greater than the limit value, the optimized current is the same as the reference current, but if the real angle is less than the limit value, the optimized current is chosen to avoid saturation. The limit value is chosen to be greater than a threshold at which the thyristors misfire, calculated as the lower retarding angle (ainf) plus a margin ( DELTA alpha ) of 2-7 deg . A correction proportional to the difference ( delta  alpha ) between the limit and real retarding angles is used to determine the optimized current. An optimal voltage (Uopt) is also calculated and the furnace is controlled so the operating voltage (U) is no greater than the optimized value (Uopt). The minimum optimized angle ( alpha opt) is determined as a function of the optimized voltage considering the lower limit of the retarding angle and ensuring the optimized angle is 10-90 deg  and greater than or equal to a reference value ( alpha ref). Independent claims are also included for a device for carrying out the above process and an arc furnace containing the control system

The method is designed to be used in electronic devices carrying out calculations of the type with or without results in place. The method is applied to an power function algorithm according to a binary method or k-range with bit or figure number (ri) sweep from left to right. The indexed register is obtained from the value of the indexed bit or figure (ri). The bit sweep for the number r may be from right to left and the indexed register is obtained from the complement of the value of the indexed bit.

IPC: B60H1/32
Filed: 2001-06-14
Abstract: The condenser fan speed regulating device (10) regulates the speed to a continually varying intermediate value, in order to always minimise the total electrical consumption (W) of the air-conditioner.

These data allows obtaining of a statistical regression formula between the voltage (Vfan) and the different parameters, which minimises the total consumption (W).  The air-conditioner has a main control unit (10) and a refrigerating circuit (7) having a variable cylinder compressor (5), a condenser (3), a pressure relief valve (6) and an evaporator (2). The condenser is cooled by the condenser fan (8).
