灯泡贯流式机组一次调频性能优化试验研究

灯泡贯流式机组的低水头运行特点在一定程度上限制了其一次调频性能，往往会使其一次调频的考核指标欠佳。对此，通过对灯泡贯流式机组一次调频的控制逻辑进行理论分析和仿真模拟，在保证机组安全稳定运行以及满足电网考核指标的前提下，对调节速率和调节深度的影响因素及其解决方案进行了研究。经过在真机上对研究结果进行试验验证，结果表明：机组一次调频性能得到了改善，一次调频动作后的积分电量得以增加，实际效益也因此得到了提升。研究成果可为今后开展的灯泡贯流式机组的一次调频性能优化工作提供参考与借鉴。

Experimental study on performance optimization of primary frequency regulation of bulb tubular uni

The operation characteristics of bulb tubular units with low water head limit the performance of primary frequency regulation to a certain extent and often result in poor performance of primary frequency regulation examination. Through the theoretical analysis and simulation of the control logic of the primary frequency modulation of bulb tubular unit, this paper studies the influential factors of the regulation rate and depth and their solutions under the premise of ensuring safe and stable operation of the unit and meeting the requirements of the power grid assessment index. The real machine test show that the performance of primary frequency regulation of the unit is improved, the integral quantity of electricity increase after primary frequency regulation operation, and the actual benefit is improved, which can be used for reference for optimizing the performance of primary frequency regulation of bulb tubular units.
