る。[Prior art] Figure 3 shows automatic voltage control (hereinafter referred to as VR control) for stabilizing the voltage of the power system against fluctuating loads such as AC regeneration vehicles.
An example of the method is shown below. Corresponding to the load 4 such as an AC regeneration vehicle loaded on the feeder line 3 connected to the power source 1, a thyrisk switch 14 in which a reactor 13 and a thyristor are connected in anti-parallel to the feeder line 3 or the same level track is installed. Thyristor-controlled reactors connected in series! 2 (hereinafter referred to as 701 section), and a harmonic filter section I5 is connected in parallel with this. Note that 2 is the percent impedance on the power supply side (

An equal reference value Vref is set corresponding to the detected voltage signal Vl based on L, and the difference signal ΔV is obtained by the voltage fluctuation adder 7, and the difference signal ΔV is P! The output is input to a controller 8 to be controlled, and its output is input to a function circuit 9. In the function circuit 9, in order to compensate for fluctuations in ΔV by changing the current flowing through the reactor 13, the voltage signal is converted into a voltage signal corresponding to the firing phase angle of the thyristor that generates the current, and is output to the next control pulse generator. Synchronous power supply circuit input to 10 and connected to Pτ5! 6, a thyristor phase control pulse corresponding to the ignition control phase angle is outputted by the synchronization signal S. This control pulse is applied to transformer 11
is output to the gate terminal of the thyristor 14 via the thyristor, which fires at its phase control angle.

At this time, the output from adder 7 becomes large, and P! The output from the controller 8 increases, and due to the increase in the input to the funxilon circuit 9, the phase of the firing pulse of the thyristor in the pulse transformer 11 is delayed, so that the current flowing in the reactor 13 decreases, From the perspective of the power grid, the idle component has the same capacity as before the load change, and the grid voltage is controlled to a constant voltage.

When the feeding voltage varies slowly, the control voltage signal from the continuous control section 17 is applied to the adder 1.
9, which is converted into a control voltage signal corresponding to the negative phase of the firing phase by the function circuit 9, and its output is converted to the firing phase angle of the thyristor by the pulse generator 10 according to the reference signal from the power supply synchronization circuit 16. converted and generates a pulse. This firing phase angle pulse is transmitted to amplifier 21. The reactor is sent via the pulse transformer 22 to the thyristor switch 13 and controlled by the thyristor! 2 continuous energization control is performed.

上昇するように制御される。The fluctuating feeder line voltage signal V from the voltage detector 6! is input, the difference voltage between the reference value Vrefl and Vl from the reference value setting circuit 23 is determined by the adder 24, and this difference output is used as the PI
Adder through m-segment 1?1! 9 is a continuous control section, and this Vl and Vref2 (1,05pu setting) or Vref3 (0,95pu setting) and comparator 2
8 or 29, for example, an instantaneous voltage drop occurs and v
When I becomes 95% voltage or less (0.95 pu), the comparator 29 operates, and the 121J relay (an electronic switch may also be used), which turns on at 10, turns on. (0,025Pu)31 is added to the adder 19 via the adder 32. As a result, the slow phase bone is added to the input of 9, and the firing angle β of the TCR thyristor becomes large.
The current flowing through the accelerator of the TCR section is controlled to decrease and the grid voltage is increased.

The LIJ relay that turns on at 10 turns on, and at this contact a, Δ
The phase advance setting (0,025 pu) 30 is added to 13 through an adder 32. As a result, the leading phase is added to the input of 8, the firing angle β of the TCR thyristor becomes small, and T
The current flowing through the CR section saddle increases and the system voltage is controlled to decrease.
前述Δ遅相設定分、Δ進相設定置を夫々、0.025p

、段階制御の役割は、本例では35%〜105%の電圧
変動の抑制は連続制御系が優先し、35%以下及び10
5%以上の電圧変動に対しては段階制御が優先して制御
することとなる。The aforementioned Δ slow phase setting and Δ advanced phase setting are each 0.025p.
The reason for selecting u is to consider the hysteresis characteristics in cooperative control with continuous control and stepwise control. The role of continuous control and stepwise control is that in this example, the continuous control system gives priority to suppressing voltage fluctuations of 35% to 105%, and the suppression of voltage fluctuations of 35% to 105%
For voltage fluctuations of 5% or more, step control is given priority.

。[If the operating voltage drops slowly below the rated voltage, PI controller 17! A control signal is output, and the feeding voltage is corrected in the direction of the rated voltage, but there is a rapid transient voltage fluctuation, and the feeding voltage drops to 0.95V! When it is turned off, a control signal for lowering the reactor current by 0.025 pu is output from the level setter (Δ slow phase setting) 31 to the adder 32 in response to the rising signal from the comparator 29, and is input to the adder 19.

In other words, the continuous control system can follow the electric voltage by 0.95V! Control so that the above is achieved. Feeding voltage is 0.95V1 or more (t

In other words, the control operation is performed only by the continuous control system. The reason why the stepwise control system performs priority control is that there is no time delay in comparators 2B and 29, and the PI of the continuous control system
