| 摘 要： | 文章介绍了一种不依赖自身电量的注入式转子接地保护的新方案，分析表明该方案有较好的故障反映能力。其特点是，在机组停机情况下能够检测出转子接地情况，克服了常规乒乓式原理在机组停机情况下无法运作的缺点。在实验室中的试验结果表明理论与实验相符。

| Abstract: | The article introduces a new-brand scheme of injected rotor ground protection that not-dependent on its own power capacity. The analysis demonstrates that the new scheme can reflect the error timely and effectively. The new scheme ean report the ground connection status of the rotor in outage time. This has tackled the challenge that the conventional method can not tell the connection status in outage time. What has been found in the laboratory gives evidence to back up the rationale. |
