结合图13所示,一种基于上述太阳能水泵系统的控制方法,所述控制方法包括:As shown in Figure 13, a control method based on the above-mentioned solar water pump system, the control method includes:

第一步:上电程序初始化。Step 1: Power-on program initialization.

第二步:根据水泵系统的功率设置光伏阵列1工作的阈值电压和电流。Step two: set the working threshold voltage and current of the photovoltaic array 1 according to the power of the water pump system.

第三步:检测光伏阵列1的实时电压和电流,若实时电压和电流未达到阈值,则太阳能水泵系统不工作,若实时电压和电流达到或超过阈值,则太阳能水泵系统开始工作。Step 3: Detect the real-time voltage and current of the photovoltaic array 1. If the real-time voltage and current do not reach the threshold, the solar water pump system will not work. If the real-time voltage and current reach or exceed the threshold, the solar water pump system will start to work.

第四步:太阳能水泵系统工作后,计算光伏阵列1的最大输出功率,通过不用工作电压下实际功率的变化情况控制增加或减小工作电压,若低工作电压下的实际功率与高工作电压下的实际功率的差值小于零,则可增加工作电压,若低工作电压下的实际功率与高工作电压下的实际功率的差值大于零,则可减小工作电压,循环反复判断,使太阳能水泵系统的实际功率始终接近光伏阵列1的最大输出功率。Step 4: After the solar water pump system works, calculate the maximum output power of the photovoltaic array 1, and increase or decrease the operating voltage by controlling the change of the actual power under different operating voltages. If the difference between the actual power under the low operating voltage and the actual power under the high operating voltage is greater than zero, the operating voltage can be reduced, and the cycle of repeated judgments can make the solar energy The actual power of the water pump system is always close to the maximum output power of the photovoltaic array 1 .

具体可如图14所示,Pm为最大工作点的功率,当系统工作电压从U1增加到工作电压U2,输出功率为P1变化为P2,如果P2-P1>0,说明最大工作点在实际工作点的右侧,可以继续增加工作电压。如果工作电压从U4增加到工作电压U3,输出功率为P4变化为P3,如果P3-P4<0,说明最大工作点在实际工作点的左侧,可以用负的电压差值给定,减少电压给定,这样反复操作就达到了动态跟踪最大功率的过程。Specifically, as shown in Figure 14, Pm is the power at the maximum operating point. When the system operating voltage increases from U1 to U2, the output power changes from P1 to P2. If P2-P1>0, it means that the maximum operating point is in the actual working To the right of the point, you can continue to increase the operating voltage. If the working voltage increases from U4 to U3, the output power changes from P4 to P3. If P3-P4<0, it means that the maximum working point is on the left side of the actual working point, and the negative voltage difference can be used to reduce the voltage. Given, such repeated operations have achieved the process of dynamically tracking the maximum power.

第五步:工作完成后,关闭太阳能水泵系统。Step Five: After the work is done, turn off the solar water pump system.

太阳能水泵系统的工作具有保护功能,包括外界水位保护、水箱水位保护、电机过流保护、电机短路保护、控制系统过温度保护。此外还具有远程操作、遥控操作功能。The work of the solar water pump system has protection functions, including external water level protection, water tank water level protection, motor over-current protection, motor short-circuit protection, and control system over-temperature protection. In addition, it also has the functions of remote operation and remote operation.
