【正文】 ility investment is bigger, in order to fully displays its electricity generation the efficiency, reduces system cost the recycling cycle, the electric power facility uses the maximum work rate output for the control goal. Supposes each winddriven generator and each group of solar cell arrayal works in peak power output condition, wind power generation and solar energy electric power facility output total output distinction is EMBED and EMBED , system to its use factor distinction EMBED and EMBED , then (2 3) the formula may rewrite is System structure drawing like chart 2 7 show: May know by the 27 chart, the system input value are more, in view of a wind power solar energy mix generating system characteristic, uses the graduation fuzzy control in here us the strategy to e to the system to carry on the control, and designs four level of graduation fuzzy controllers to realize to mixes the generating system to carry on thee energy management and the control. System structure drawing like chart 2 8 show: The burden of the system is to be provided directly by the direct current electric power and through go against to change the machine exportation, the stability of the direct current electric voltage bees direct influence39。t be use directly to control to be control object, must still convert the certain control measure, we be called this process to solve the faintness or faintnesses to measure clear to turn. Usually reason logically and the exportation carries to have to convert the misty quantity as clear value of process be called the solution faintness. 4. Designs of the ＥＭＳ This article designs the wind can a solar energy mix generating system structure diagram like chart 2 6 show For the sake of the exaltation can the exploitation efficiency of the renewable energy, under the condition that wind energy and solar energies can satisfy to load the request, the load then is provide by the wind energy and solar energy the demanding energy。) Then (control measures is c。s intuition inference one language expression form. Most monly used is if then, else, also, or and so on, like 2 Uyghur fuzzy inference rule maybe represented as R: If (deviation is a。s experience formalization, the simulation, turns the control model and the language which the puter may accept, lets the puter replace the person to carry on the effective realtime control. Fuzzy controller position diagram like chart 2 3 show 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 measure of all misty son gather of belong to one degree relation of vector value。 make possible, lay the foundation for the formation of the misty controller, and get the scholar of the international munity and the engineering technical personnel39。 Studied and has designed one kind based on the graduation fuzzy control (Hierarchical Fuzzy Control, was called HFC) the algorithm energy management system management system. 3. Misty controls The fuzzy set with the fuzzy control concept is by American University of California famous Professor L. A. Z a d e h in it Fuzzy Sets， Fuzzy Algorithm and Rationale for Fuzzy Control and so on famously discusses center first was proposing one kind is pletely different with the traditional mathematics and the control theory intelligent theory. Its production not only developed the broad classical mathematics foundation, moreover was causes the puter science to simulate the significant breakthrough which the human thought aspect developed. The faintness gather to e out the person39。 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 i
