Embodiment Construction
[0027] Such as Figure 4 As shown, the pumping station energy-saving optimization control method of the present invention includes the following steps:
[0028] Step 1. The liquid level difference E, the liquid level change rate EC, and the number U of the pumps to be activated are divided and graded respectively;
[0029] Step 2. According to the Gaussian function, establish the membership degree table of the gear and series of the liquid level difference E, and set the gear of the liquid level difference E, the gear of the number of starting pumps U, and the gear of the liquid level change rate EC the state table;
[0030] Step 3. According to the membership table and the status table, the weighted average method is used to calculate the control relationship table for the classification of the liquid level difference E, the classification of the liquid level change rate EC and the classification of the number of pumps U;
[0031] Step 4. According to the formula y1=10 / (L2-...
