Embodiment
Graphitizing furnace as shown in Figure 1 controls power transmission system automatically, comprise the PLC control system based on the Internet, also comprise the gear controller, voltage regulating transformer and the rectifier transformer that connect successively, the signal output part of PLC control system is connected with gear controller, voltage regulating transformer is connected with PLC control system with the signal output part of rectifier transformer, and each gear correspondence of described voltage regulating transformer is provided with on load tap changer.Be provided with motor-operating mechanism between described gear controller and voltage regulating transformer, on load tap changer is driven by motor-operating mechanism.
Before production, manufacturing enterprise designer designs the power curve that will perform according to firing product type.The power of voltage regulating transformer controls on load tap changer by motor-operating mechanism have been come.The active power that each gear of voltage regulating transformer is corresponding is equivalent to the discretization to power curve, and increment size is that current voltage regulating transformer is transferred the files the transient change value of changed power, and after transferring the files, power also will change with temperature dynamic.In sintering procedure, the value of control system sample-power curve and the value of actual active power compare.When meeting upshift condition, send upshift operation instruction to gear controller by PLC control system, gear controller sends instruction again to motor-operating mechanism, operates the switch of corresponding high gear, completes shifting up operation; When meeting downshift condition, send downshift operation instruction by PLC control system and make to gear controller, gear controller sends instruction again to motor-operating mechanism, operates the switch of corresponding low gear, completes downshift process.Meanwhile, control system also detects voltage signal, current signal, temperature signal and the alarm signal etc. that rectifier transformer and voltage regulating transformer send, and judges and send command adapted thereto to gear controller according to signal, controls on load tap changer action.
The important parameter affecting real-time active power has: the resistance of voltage, stove, time, i.e. Load_real(U, R, t).Curve is shown in Fig. 2.Boost action occur after, power is step function, after present ascendant trend by the impact that stove resistive is little.Suppose that the power increment due to boosting △ U generation is △ Load_real, in an operation cycle operation_cycle, hinder the power increment affected by stove is △ Load_real '.Algorithm is as follows:
