英语翻译
The use of a Iow-power low-voltage dc link in parallel with a high-voltage high-power ac line is found to be a means of ensuring the improved dynamic stability of the ac line.A new approach is proposed where the dc power would be transmitted not over a separate dc line but superposed on the ac line by injecting into the transformer neutrals at the two ends.A Simple control strategy was utilised and fine tuning has not been attempted at this stage.
Advantages seen from this method of stabilisation are that it does not adversely interfere with the nominal function of the generators excitation system and that the generator will not be subjected to pulsating shaft torques during disturbances.
The proposed controller will have a high bandwidth compared with PSS and therefore could also be used to damping of higher frequency oscillations such as SSR (with dc bypass inductors across the Compensating capacitors).
Modelling and simulation of the system and controllers were done with the electromagnetic transient program EMTDC/PSCAD.

采用低功率低压直流线路与高压大功率的交流线路并联的连接不失为一种保障交流线路得到加强动态稳定性的方法.对于直流电源的供给,非经过一条独立的直流线路,而是通过将其注入在变压器两端空档、将其叠加在交流线路上的方法已被推荐采用.过去一段时期内,人们所使用的只是一种简单的控制策略;而在现今,更好的调节方法至今还未在此领域中被尝试.采用此种稳定方法的好处有两个:首先它不会对发电机组激励系统的标称功能产生恶性干扰;其次,发电机无需受制于在干扰过程中所发生的轴扭矩.
相对PSS来说,该控制器的频宽较高;其也可用于更高振动频率的减幅,例如SSR,(通过将直流分流器导体穿过补偿电容的方式).
建模、系统与控制器的模拟已通过电磁暂态程序EMTDC及PSCAD完成.
