2) electric energy quality monitoring parameter, device parameter and environmental parameter are acquired；
3) power quality basic index and standard value are compared, warning is then issued more than limit value and handled, not exceeded, then root
The predicted value of power quality index is calculated according to performance prediction model, and combines central air conditioning equipment parameter, environmental parameter, according to strong
Light current converts distributed model and carries out trend analysis to monitoring data after central air-conditioning power electrotransformation；
Wherein, performance prediction model is to obtain central air-conditioning electric energy strong and weak electricity by establishing multiple linear regression parameter model and turn
Change the power quality function of terminal, power quality function Q (t) is expressed as follows:
;
It X(t) is central air-conditioning electric energy quality monitoring parameter,For regression coefficient,To return harmonic coefficient；
Wherein, grid-connected rank function R (t) used by grid-connected distribution of grades model are as follows:
For power quality function first derivative, a, b, c is harmonic coefficient；
4) warning index is calculated, and is compared the out-of-limit situation for obtaining each index with the limit value in early warning knowledge base；
5) according to warning index calculated result and out-of-limit situation, the rule in early warning knowledge base is matched, identifies abnormal cause；
6) counte-rplan for most matching current abnormal cause event are hunted out from early warning knowledge base；
Wherein, the implementation that analytical unit carries out intelligent Evaluation to the power quality after strong and weak electrotransformation is following steps:
1), verify power quality parameter, device parameter, environmental parameter initial data；
2) stereochemical structure, is established, with frequency quality, tri-phase unbalance factor, harmonic content, voltage in power quality in stereochemical structure
Fluctuating range is primary element, using central air conditioning equipment parameter and environmental parameter as minor element；
3) single index calculating and scoring, are carried out；
4) weight coefficient in discrimination matrix and stereochemical structure, is constructed；
5) weight coefficient, is corrected；
6) comprehensive effectiveness for, determining central air-conditioning forceful electric power conversion light current, is as a result shown by display unit.
