| 摘 要： | 介绍了一种应用于塔式太阳能热发电系统的水/蒸汽吸热器过热蒸汽温度控制系统。受到太阳辐射能间歇性和不确定性的影响,吸热器产生的过热蒸汽温度难于控制。控制系统根据吸热器在蒸汽流量变化、光功率变化和减温水流量变化等3种主要扰动下的过热汽温度动态响应特性,以减温水流量作为控制量,光功率和蒸汽负荷作为前馈信号,设计和研制了两段式过热蒸汽温度控制系统,使吸热器过热区出口汽温维持在允许的范围内。

| Abstract: | A superheated steam temperature control system of heat receiver in solar power tower plant was introduced.It is hard to control superheated steam temperature of receiver because solar radiant energy is intermittent and unsteady.A superheated steam temperature control system with two phases was designed and developed based on dynamic response characteristics of superheated steam caused by three main influencing factors such as steam flow,solar radiation and flow of desuperheating water.The flow of desuperheating water was used as control variable,and solar radiation and steam load as feed-forward signal,the steam outlet temperature at superheat zone in receiver changed within allowable arrange. |
