辅机故障快速减负荷调试方案的改进及应用

Improvement and Application of Commissioning Plan for Auxiliary Equipment Failure Run Back

介绍了国内超(超)临界直流机组辅机故障快速减负荷的试验方法,通过更为合理的机组快速减负荷(RB)功能试验逻辑的设计改进和试验的有效组织,使超(超)临界机组RB功能试验更为安全,试验的质量控制更加严格,现场使用更加可靠,降低机组因RB实际动作时意外跳闸的可能性,形成一套科学的、完整的、系统的RB功能试验方法,为今后基建阶段超(超)临界机组的RB功能试验提供调试经验。

A commissioning method for auxiliary equipment failure run.back （RB） in ultra-supercritical unit is introduced. With the improvement design of the RB control logic and effective organization of RB test, it makes the ultra-supercritical unit RB test more safe, test quality control more strictly and the RB function application more reliable. The probability of unit accidental trip when RB happens is reduced. A set of scientific and systematic RB commission method is formed, which can provide reference of RB test for ultra-supercritical unit during construction period.
