摘要(Abstract)：

针对电制热熔盐储热发电系统的动态特性展开研究，建立了蒸汽发生系统、发电系统的动态模型，验证了模型的可靠性。分析了熔盐工质流量、温度和蒸汽阀门开度扰动下的动态特性，并研究该系统在100%THA—50%THA负荷区间的降负荷瞬态过程性能。研究结果表明，在熔盐温度扰动下，主蒸汽温度和再热蒸汽温度快速响应，且明显快于机组负荷和主蒸汽压力响应；熔盐流量扰动对机组负荷和主蒸汽压力具有显著影响，熔盐流量增加15%时，机组负荷增加12.44%，主蒸汽压力增大1.18 MPa；主蒸汽调节阀开度则控制着主蒸汽压力和负荷波动。在温度偏差的限制条件下，100%THA—50%THA负荷区间的最大降负荷速率达14%P_e/min。
