1、 英文翻译 1 Energy Management System of Admixture Electricity-generating 1. One preface The admixture that wind force and solar cells generate electricity to constitute generates electricity the system and is called the breeze/ light to repair the system with each other, all having some common weakness
2、because of the breeze and solar energies, such as the energy density low, the stability is bad and is subjected to the weather influence not to continue, have the strong weak conjugation, solar energy of seasonal to interrupted etc. day and night. Be generate electricity by the wind force and solar
3、energy respectively to the power supply, the credibility of its power supply lowers consumedly. The wind energy, solar energy has to repair sex with each other certainly, if the sun light of daytime is strong, the night breeze is many, the summer sunshine good, the breeze is weak； The spring stanza
4、breeze of winter is strong but the sunlight is opposite weaker. Develop the wind force a solar energy to supply again to give or get an electric shock the system with each other, take into wind force and the solar energy techniques to synthesize the exploitation, thus constitute a kind of repair wit
5、h each other of can scatter the new energy that cloth order, will is a new growth to order in this energy structure of century. Have the condition pass the storage battery of match the appropriate capacity or connect into the city to give or get an electric shock the conduct and actions back up powe
6、r supply, can make circulate the expenses to lower consumedly, huge exaltation of the credibility of the power supply. Local mainly generate electricity to independent wind power, the light currently and the breeze a light supplies again the research of the electricity control system with each other
7、 more. In design the breeze a light generate electricity system, the design way of thinking of the widespread adoption according to load everyday total to consume the electricity quantity, and radiate the quantity from the day that the local weather data get to the capacity of the certain solar cell
8、 array, the wind power machine, then come certain can the renewable energy generate electricity the power and the storage battery 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. Beca
9、use 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 compare greatly, as a result turned the energy of generate electricity the system management to also put forward the higher request to
10、wards control and excellently. This text aims at the movement efficiency and credibilitys that the characteristics of the system movement designs one energy management system( energy management system, brief name EMS) to raise the system. 2. composing of the systems This text with the south science
11、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: 2 May known by the chart 2-1, the system includes following several parties:
12、 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 electr
13、icity 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
14、 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 syst
15、em 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
16、 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 n
17、eeds, when the renewable energy output electrical energy has the unnecessary energy, only then invests load. The system load and the direct component 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
