Beschreibung
Zusammenfassung:	The invention discloses a water chilling unit group control optimization method based on load prediction, and the method comprises the following steps: building a load prediction model and a water chilling unit load matching model based on historical operation data and a water chilling unit characteristic curve; according to historical operation data and building characteristics, parameters such as indoor and outdoor air temperature and humidity, heat dissipating capacity of indoor personnel and equipment and the like in a future period of time are input in real time and substituted into the established load prediction model, and the predicted cooling capacity of the air conditioning system is output; according to the predicted cooling capacity, an optimal starting scheme is given in combination with the established water chilling unit load matching model, and the number and the model of the started water chilling units are controlled; and comparing the actually measured cooling capacity with the predicted co
