【正文】 attery capacities of control the devices, but at mix with the movement of generate electricity the system control and excellent turn the research of manage the method less. Because the exportation power and the burden powers of the breeze electrical engineering set, the solar cell array is affect by the outside factor, changing the scope to pare greatly, as a result turned the energy of generate electricity the system management to also put forward the higher request towards control and excellently. This text aims at the movement efficiency and credibility’s that the characteristics of the system movement designs one energy management system( energy management system, brief name EMS) to raise the system. posing of the systems This text with the south science and engineering university dispersion type wind force a solar energy of the new energy center admixture generates electricity the system for study the view, the structure diagram of the system, such as 2 － 1 of figure 1 show: May known by the chart 21, the system includes following several parties: The wind power machine and its controller: Total 15KW / sets of the biggest exportation power of the breeze machine, the wind force machine generates electricity the controller to make the wind force machine been placed in the biggest power to output the appearance always. Solar cell and its electricity generation controller: The altogether 5 groups, solar cell each group of peaks tile 3 k W, the solar energy electricity generation controller causes the solar cell array throughout to be at the maximum work rate output condition. The data collects the system:( the data acquires the system, the brief name DAS)Used for the electric voltage, the load power that collects to examine the solar cell exportation power, the wind power machine to output the power, the system direct current part, and circulate the relevant information to the system that collect, providing the energy management system to carry on the analytical processing. The energy manages the system: collect each function of system unit movement parameter that system provide according to the data, carry out the valid management to the system and controls. Buffer electric capacity: carry out parts of electric voltages of the system direct current steady. Load and inversion: The new energy center load classification, a kind of load is a load which the energy center work and the experiment must guarantee。 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, transforms for the voltage is constant, the profile good exchange electrical energy, provides for the load. The city gives or get an electric shock the controller: When can the electricity that renewable energy provide can satisfy a load of system need, giving or get an electric shock from the city to make the plement。 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。 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。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。) Then (control measures is c。t satisfy the load request, at making use of well can the foundation of the renewable energy up, the load is provided together by the wind energy, solar energy and charged barbed wire s the demanding energy. May know by the system structure drawing, the system direct current generator voltage change direct influence system provides the electrical energy to the load the quality and the reliability, thus the stable DC voltage is the system operational reliability and a performance important target.
