三峡-葛洲坝梯级电站联合调度水力学模型试验中，三峡电站下泄流量日变化幅度较大，葛洲坝电站反调节时流量大而水头较低。针对上述特点，分别采用不同的设计原理和控制方法，较好地解决了两电站流量的自动控制问题；针对两坝间及葛洲坝下游非恒定流水力学参数的测量，采用超声水位传感器和二维流速传感器实现了集中实时测量并自动处理输出，软件采用模块设计。整个系统简单、清楚、高效,并举实例说明自控及测量系统的应用。

In the Three Gorges Project (TGP)Gezhouba Project(GP) step power station cooperation hydraulics model test, daily Changing amplitude of TGP power stations releasing discharge is large and that of Gezhouba Project in its reverse regulation is huge with low water head. Aiming at the above mentioned features, different design principles and control methods have been adopted respectively to solve the automatic discharge control problems for two power stations. For the measurement of unsteady flow hydraulics parameters in river between two dams and downstream Gezhouba reach, the supersonic water level sensors and twodimension velocity sensors were used to realize concentrative measurement in real time and automatic data processing. The software adopted modular design. The whole system is simple, clear and efficient. An application example for showing the automatic control and measurement is given.
