Abstract: In order to solve the problem of storage capacity configuration in distributed photovoltaic energy, firstly a brief introduction of the storage methods in distributed PV (photovoltaic) energy is given out. Then it mainly discusses the configuration mode of distributed photovoltaic battery energy storage capacity within a variety of methods and principles of the research situation. And their advantages and disadvantages are analyzed in detail. Finally, the energy storage capacity configuration problems to be solved in the future development and its application should be made to focus on the aspect shortly.

Abstract: The design scheme for PV system connecting the grid is provided, considering the reactive power compensation, harmonic and lightning effects. Solar power generated connects into the nearby medium and low voltage distribution networks by the inverter. The capacity of solar power total is 1.15MWp. The electricity is generated for personal use; the remaining is connected to the grid system. The scheme is reasonable in design; the system is stable and reliable by the practical testing. It can be used in large range popularization and application.

Abstract: With the rapid development of computer technology and network technology, mass data store distributed and management pattern already received accepted extensively. Thus it can be seen malpractice obviously, data storage structure, storage environment are different and other problems such as data handing. The paper go into how improve data storage performance in the distributed environment, analysis the data storage technology at present and data storage performance in the distributed environment, summarize the claim of distributed storage database design, provide the theory in vacation distributed data storage performance standardization.

Abstract: Distributed way of traveling-wave fault location algorithm is a new theory founded in recent years. By installing sensing points in distributed way, the accuracy of fault location result can be clearly improved comparing to traditional methods. First, PSCAD is used to simulate the transmission line model and measure the three-phase current data. Second, by using wavelet transformation and phase to-module transformation, these current data is mathematically processed and modulus maximum is achieved easily. Finally, time difference between the adjacent modulus maximum points is calculated and the location is figured out by using the module time-difference algorithm. The test result shows that the method above is valid and the relative error is rather small.

Abstract: With the widely applied computer control system, especially the distributed control system, the complexity of control software is becoming higher and higher, and the quality of the software directly affects the reliability of control system. This paper develops a new traceability system for food processing by using VB programming software and CMM computer software testing technology, and sets up the quality traceability control model of food processing, which realizes the optimal allocation between the raw material batch and the order. Quality traceability system for CMM food processing designed in the third section is verified. The traceability of the quality in the process of food processing can adjust the process of food processing, so as to obtain new quality curve, and to provide a theoretical basis for the research on the quality control of food processing.

Abstract: Big Data provides a possibility of handling mass data, which acts as a subversive technique. By the way, traditional relation database is no more effective of mass data that causes distributed database NoSQL to appear and evolve. In this article, we will design and realize a new distributed big data management system (DBDMS), which is based on Hadoop and NoSQL techniques, and it provides big data real-time collection, search and permanent storage. Proved by some experiment, DBDMS can enhance the processing capacity of mass data, very suitable for mass log backup and retrieval, mass network packet grab and analyze, and etc. other applied areas.

Abstract: Beacause internet data has a massive, diverse, heterogeneous, dynamic features, using traditional databases to analyze these data, data storage and processing efficiencies already can not meet the requirements. Utilizing leading-edge distributed computing technology to solve traditional data mining scenarios in lack of data mining of massive data improved data mining algorithm of lot OK Hadoop distributed computing platform, which later on other data mining algorithms using Hadoop to reference while using rich data mining algorithms can be found there is more value in your data.

Abstract: According to the problem that test system synchronization accuracy requirements are increasing. This paper designed a precise time stamp measurement systems that use hardware at the bottom to join timestamp in order to eliminate software latency effects, point to point and multipoint timestamp synchronization via synchronization algorithm based on prediction.

Abstract: The software sharing is the development trend of tracking telemetry and command software. How to develop quickly the tracking and controlling tasks software to adapt to the current experimental situation, and to ensure software quality, is a challenging subject placed in the face of software personnel. Using software middleware and software component technology, we can solve the problems of Tracking and Controlling Network acrossing operating system, Tracking and Controlling Software acrossing program languages, software reuse and other issues.

Abstract: The network economy era brings new challenges to all aspects of society, and the construction of network culture industry also brings an urgent request. Due to the complexity of network culture industry, the construction and study of cultural network industry has certain challenging. In order to realize the massive network industrial data analysis, we introduce the genetic algorithm into the network control model, and put forward the distributed network control model based on genetic algorithm, which can realize the massive data analysis. In order to verify the effectiveness of the algorithm, this paper uses MATLAB genetic algorithms toolbox to debug the algorithm, and obtains the genetic algorithm fitness curve and the data transmission quantity statistics. It provides the theory reference for the construction of network culture industry.
