摘　　要：首先以某柔直工程为研究对象,进行了柔直换流阀塔配水系统设计。其次对配水的均匀性进行了仿真研究,各模组流量在16.5 L/min左右,流量偏差率为3.9%,流量不均匀度为1.9%,各模组流阻在160 kPa左右,流量分配均匀。最后搭建了阀塔,测试了阀塔各模组的流量,流量在16 L/min左右,流量偏差率为4.2%,不均匀度为2.2%,流量分配均匀,仿真值和实测值较接近,最大偏差为3.1%。仿真和测试规律吻合:远离主进水管的模组流量要小于靠近主进水管模组流量,同一层呈现逐渐下降的趋势。由此可知,仿真计算可靠,可用于指导设计。First,a flexible straightening project was taken as the research object,and the water distribution system of the straightening converter valve tower was designed.Secondly,a simulation study on the uniformity of water distribution was carried out.The flow rate of each module was about 16.5 L/min,the flow deviation rate as 3.9%,the flow unevenness was 1.9%,the flow resistance of each module was about 160 kPa,and the flow was evenly distributed.Finally,the valve tower was built and the flow of each module of the valve tower was tested.The flow rate was about 16 L/min,the flow deviation rate is 4.2%,the unevenness is 2.2%,and the flow distribution was even.The simulated value was close to the measured value,and the maximum deviation was 3.1%.The simulation and test rules were consistent:the flow rate of the module far away from the main water inlet pipe was smaller than that of the module near the main water inlet pipe,and the same layer showed a gradual downward trend.It could be seen that the simulation calculation was reliable and could be used to guide design.
