摘要
介绍了某电厂660 MW超超临界机组引增合一改造后快速减负荷(RB)试验的技术方案、主要过程及参数变化,对试验结果进行了分析。结果表明:该机组改造后RB自动控制调节性能良好,能够满足事故工况下机组负荷快速降低至实际所能达到的出力。
An introduction is presented to the technical scheme, main process and parameters variation of the runback （RB） test after integration of the induced draft fan and booster fan in a 660 MW ultra- supercritical unit, while the test results are analyzed. Results show that the unit has good RB performance after integration retrofit, and the unit load can be quickly reduced to actually achievable values under accident conditions.
