Campus grid solar power plant design model


Education and role model, we developed parameters of Figure 5 Power LED display screen functions can be solar grid inverter operating parameters of real-time display on the screen. Mainly by the CPU control board within the circuit, LED driver board and DC power supply. ? Display data (see Table 1) * means of communication and agreement within the RS 485 communication protocol for a remote monitoring and data communications 2.6 modern grid-connected inverter usually provides RS232 or RS485 communication interface for monitoring and data collection inverter and display provides a way. In addition, in order to facilitate management and data collection,[link widoczny dla zalogowanych], we developed a remote monitoring and data acquisition system, the principle of the system shown in Figure 6. IP serial device uses a software company in the Division IPS201 products, the product serial port can be displayed in Table 1 shows the contents of the scope of overflow handling real-time power k, fO0000 - 99999 total generating capacity overflow zero savings kWh0.0O00--99999 SCE kg0.0000-99999C02 reductions kgO0000-99999 Figure 6 Figure 7 Principles of remote communication software flow chart of communication protocols into Ethernet protocol, the Internet provides a shortcut for traditional equipment. IPS201 provides a Telnet log management and configuration, TCP / IP protocol to transfer data and other functions, on this basis, we developed 7BE server-side data reception and processing procedures, real time power generation, the cumulative generating capacity of the inverter output ac current , voltage, frequency, solar cell output voltage, current, operating status display data is saved to the database, and published through the web site to the Internet, in any machine connected to the INTERNET to browse and query data and state power. 1) IPS device selection IPS201 work provides two connections, TCP and UDP mode mode is set to TCP, the IPS201 Server ways to reduce server overhead, easy to access in a different address, and because TCP There are connections to send data to ensure accurate receiving continuous and no duplicate data. 2) data analysis and the MySQL database storage is an excellent database system, the small size, fast, stable and reliable, providing a variety of connectivity options, support the common query language SQL. Program data is received first by the agreed format for effective data validation, and parsing the data to get a variety of electrical parameters of power, and open the database connection to data storage. 3) data using Perl language query and browse the data displayed Power website design procedures, the data curves generated automatically refresh in real time and history queries. 3 Conclusion Nankai University campus solar energy demonstration fusion power plant design construction integration, remote monitoring, remote data acquisition and real-time display and other advanced technology to achieve a fully automated unattended goal. Has the power grid and data access capabilities. Nankai University has also built the first dedicated domestic solar power station site, set outreach, teaching and research in one, running through the Internet will power the data saved to the database, and published through the web site to the Internet, in any machine connected to the Internet visit and check station data, comparing curves and status graphics, data sharing. (Web site address: Http: ∥ 202.113.24_21) of the plant built the first university in Tianjin, with a strong demonstration effect, in the field of energy saving will also have a good social benefits. According to estimates, 4.1kW solar power system, power generation per year in Tianjin 451OkWh,[link widoczny dla zalogowanych], equivalent to saving coal-fired 2.255t, reduce the coal produced CO20.681t,[link widoczny dla zalogowanych], SO20.123t, COz emissions reduction equivalent to planting 697m . The future of a family household use of solar grid solar power station in the 2 ~ 4W. Between solar and grid power believed that with the popularity of the system,[link widoczny dla zalogowanych], will produce huge economic and social benefits.
