| 中文摘要: |
| 江苏徐塘发电有限公司6、7号机组在取消脱硫旁路后对脱硫保安段电源进行改造。将脱硫保安段从原有的一段母线开断为两段，实现保安6、7段相互备用，同时热控DCS增加了脱硫保安6、7段失电连锁逻辑和供电恢复逻辑。通过现场试验验证和实际运行情况比较，脱硫保安段供电具有较高的安全性和可靠性。 |
| 英文摘要: |
| The power supply of desulfurization security segment of the 6th, and the 7th generator set of Jiangsu Xutang Power Company Limited is reformed after the abolition of the desulfurization bypass. The original bus of desulfurization security segment is broken into two to realize mutual standby between the 6th and 7th security segment, and thermo controlled DCS increases the chain logic of the loss of power and power recovery logic in the desulfurization security 6th and 7th segments. Through the field verification and the practical operation comparison, the desulfurization security segment has a high safety and reliability power supply. |
