2. Control strategy
The proposed method improves the dynamic stability of the ac system by transmitting a suitably modulated dc power in the ac transmission line by injection into the transformer neutrals at either end.
Fig. 1 shows the ac transmission line together with the dc circuit.
The proposed modulation has been incorporated in the rectifier control (Fig. 2)
The generator-ac system behaviour (linearised for small signals) is governed by the swing Eq. (I).
If the dc power is controlled proportional to the rate of
change of the variation of the transmission angle A,and the mechanical power input assumed constant during the dynamic condition, we obtain the condition, as given in Eqs. (3) and (4).2。控制策略

该方法提高了系统的动态稳定性通过传播一种交流直流电源的适当调制交流输电线路的中性喷射入变压器两端。

图1显示了交流输电线路连同直流线路。

该调制已被纳入了整流器的控制(图2)。

linearised generator-ac系统的行为(对小信号)是由摆动式。(我)。

如果直流电源控制的速度成正比

变化之变异传动角,以及机械输入功率的动态条件假设恒定一致,我们所得到的条件下,按所给的Eqs。(3)及(4)。

An electric power system (or simply power system) is a network of electrical components used to supply, transmit and utilise electric power. The quintessential example of an electric power system is the network that supplies a region's homes and industry with power - for sizable regions, this power system is known as the grid and can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centres to the load centres and the distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings and homes. The majority of these systems rely upon three-phase AC power - the standard for large-scale power transmission and distribution across the modern world. Specialised power systems that do not always rely upon three-phase AC power are found in aircraft, electric rail systems, ocean liners and automobiles.
