【正文】 It include: The importation quantity faintness turns to connect, knowledge base( database and the rule database), reason logically the machine to reach agreement the faintness to connect. (1)The faintness turns to connect The importation of the misty controller is usually certain quantity, must after faintness turn change into the language that controller know or change the quantity then can be use by the controller, the faintness turns to connect is to convert the certain importation quantity as the faintness to measure, it is also the importation of the misty controller to connect. (2)Knowledge base The knowledge base description form mainly has two kinds of: Database and rule database. Database is deposits all importations and output to change to meas ure of all misty son gather of belong to one degree relation of vector value。 EMBED ＝１ mean that two loads connect into the admixture to generate electricity the system devotion work, EMBED = 0 mean that two loads generate electricity the system excision from the admixture. Aim at the characteristics of the system movement, draw up the following design rule: (1)Rule a A power of the breeze electrical engineering capacity that constitutes to mix with to generate electricity the system is more and greatly, as a result the choice regard a power supply of the breeze electrical engineering as principle, the solar cell array is the energy tiny adjust the part. (2)Rule two According to the system work characteristic, takes the direct current side terminal voltage EMBED expected value is 216 V, when the renewable energy may output the maximum work rate is bigger than the load request, the renewable energy to the electrical work does not transport the electrical energy. (3)Rule three Takes when here the direct current generator voltage is lower than 192 V, through incorporates the controller to put through the electrical work, by the city electricity supplemented the load needs the short partial electrical energies, and the incorporation controller which the chapter introduced by this article behind causes the direct current generator voltage to maintain 192 V, namely EMBED ＝１ When attracts 200 V, closure incorporation controller, then EMBED = 0 (4)Rule four Two loads are several: Generate electricity the system for the admixture in the electric power that the assistance facilities need, when can the renewable energy exportation electric power contain surplus of energy, the load that just throw in. In two kind of loads working condition, its load power examination has not been more difficult, in order to avoid two kind of loads frequently throwing 。 EMBED 和 EMBED give or get an electric shock the switch control to change the quantity for the city respectively and two the types load of provide the rate, this text define EMBED 、 EMBED for the switch function, take the value 0 or 1。 When the renewable energy cannot satisfy the basic load request, in fully uses the renewable energy under the premise, is insufficient partially carries on the suitable supplement by the city electricity, takes the system the biggest load is 750 kW. In the power supply system, the system electricity generation and the load active power balance, is the system safe stable movement essential condition. Because the system load is provides by the Divulgate after the inversion, the DC voltage stable direct influence system provides the electrical energy to the load the quality, takes the system direct current EMBED voltage in here to control for the system the quantity, and takes its operating region is 192 V 240V, chooses 216 V for the direct ponent rated voltage. In order to does not make the system the structure too to be plex, processing did not consider in here to the accumulator cell. Namely energy management system management system structure drawing like chart 2 – 2 show: EMBED , EMBED , EMBED , EMBED and EMBED difference for female line electric voltage, exportable and biggest power in the wind force machine, exportable and biggest power, system in the solar cell array of the direct current of the system a the type load the power and two loads needed need of power。 Two kind of loads are the electrical energies which energy center ancillary facilities and so on greenhouse control needs, when the renewable energy output electrical energy has the unnecessary energy, only then invests load. The system load and the direct ponent connection is, the direct current side which realizes through the inversion after PWM inversion
