Embodiment Construction

[0080] In each minimum control cycle, the central air-conditioning system has two load groups, cooling state and non-cooling state, respectively expressed as and Among them, t is the moment studied, K t and G t is the load group in cooling state and non-cooling state at time t, and the number of loads contained in it is m 1 and m 2 , the number of controllable equipment is m=m 1 +m 2 . It can be seen that as time changes, K t and G t The number of devices and their respective operating states will change, so m,m 1 ,m 2 The value will change with time t. According to the above description, the load group of all central air-conditioning equipment is expressed as

[0081] Define the operating temperature, lower temperature limit, upper temperature limit, temperature setting value, response group screening constraint temperature upper limit, lower limit, and temperature dead zone of the equipment group at time t, such as and In the formula, Respectively re...

Abstract

The invention discloses a central air conditioner variable load rate adjusting control method based on parameter serialization. The method includes the following steps that firstly, a water cooling central air conditioner unit model is established; secondly, central air conditioner variable load rate adjusting control is conducted; and the second step of central air conditioner variable load rate adjusting control mainly includes control strategies of four links including load grouping temperature priority ordering, group screening and load rate adjusting, and central air conditioner variable load rate adjusting control is achieved on the premise of considering the user comfort degree. Compared with the prior art, the central air conditioner variable load rate adjusting control method based on parameter serialization is matched with a central air conditioner load model, effective control over central air conditioner groups is achieved, and the purpose of tracking group responding targets is achieved.

Description

technical field [0001] The invention relates to the field of central air-conditioning control, in particular to a method for regulating and controlling the variable load rate of central air-conditioning based on parameter serialization. Background technique [0002] With the massive access of distributed power sources and the two-way interaction between users and the power grid, it is widely used. The initiative of the distribution network is enhanced, and the operation mode is becoming more and more complex. The traditional distribution network operation theory is no longer fully applicable, and is gradually developing towards the active distribution network theory. That is, according to the actual operating status of the power system, actively manage a large number of distributed power sources connected, and can adaptively adjust the distribution network of various resources. Load control, as one of the key technologies of load scheduling, realizes the effective integrat...
