| 中文摘要: |
| 上海发电机厂引进的西门子1 000 MW级核电机组励磁方式为无刷励磁。由于无刷励磁机及其整流盘的容量有限，励磁系统的强励能力受到限制，有时不能满足国内电网对于机组的强励要求。因而具有高强励顶值和电压上升率的自并励静止励磁系统成为1 000 MW级核电机组励磁方式的另一选择。就上海发电机厂的1 000 MW级核电机组静止励磁系统的主要部件，包括励磁变压器、可控硅整流装置、灭磁及过电压保护装置及自动电压调节器的一些性能参数作了分析探讨，为今后静止励磁系统的具体设计打下基础。 |

| The 1 000 MW nuclear generator, introduced by Shanghai Generator Works from Siemens AG, adopts a brushless excitation system. The field forcing of the excitation system for the generator is limited due to the limited capacities of the main exciter and rectifier and sometimes cannot meet the requirements of the national grid. The static self and shunt excitation system has a high field forcing factor and a high voltage rise rate, and thus it can be selected as the excitation system for 1 000 MW nuclear generators. In this paper, performance parameters of the main devices for the 1 000 MW nuclear generator excitation system were analyzed, inclusive of the excitation transformer, thyristor rectifier bridge, de-excitation and over-voltage protection, and automatic voltage regulation. |
