Applications:
It is applied in coastal beaches, Gobi wasteland and suburban open areas without shade, and it is an important part of the distributed generation system.
Solution:
The large-scale ground PV power station is composed of PV power generation system, inverter system and grid access system. Power generation system basically includes PV cells, PV array bracket, DC combiner box, DC distribution cabinet, grid-connected inverter, AC distribution cabinet, step-up transformer, etc. in addition to the power station monitoring device and environmental monitoring device.
In the large-scale ground PV power station, solar module array outputs the electrical power under the solar radiation, and the power flows through the DC combiner box into the DC distribution cabinet and is converted into AC by the grid-connected inverter, and then the power is stepped up by the step-up transformer and connected into the grid and finally transported to the end users by the grid.
Features:
Energy storage is unnecessary for the entire power generation system, and the maximum utilization of electrical energy may be achieved with the grid support;
Reliable system, easy construction and maintenance;
Centralized and large-scale power generation by solar energy, energy-saving and environmental, contributing to the national energy-saving tasks;
Help to protect the good ecological environment, and adjust the structure of energy consumption;
- Q: The production and transportation process of electric power
- Transmission lines can be divided into overhead transmission lines and underground transmission lines according to the structure. The former is composed of line tower, conductor, insulator and so on, which is erected on the ground; the latter is mainly used for laying underground cable (or underwater). According to the nature of the current, the transmission can be divided into DC and AC transmission. In 1880s, the first successful realization of DC transmission, due to the low voltage limit (the transmission capacity is roughly proportional to the square of the transmission voltage) in the end of nineteenth Century for AC transmission replaced. AC transmission success ushered in the era of electrification in twentieth Century. Since 1960s, because of the development of power electronics technology, DC transmission has a new development, and AC transmission, with the formation of AC and DC hybrid power system.
- Q: Complete sets of power equipment life of the country what are the provisions for the aging of the equipment how to deal with, there is no standard?
- Such as frequency of use, load characteristics, working environment, etc.. The service life of a certain type of equipment must refer to the specifications of the corresponding industry.
- Q: In the communication and power equipment in the data access to a "remote message quantity" concept, then what is called "remote information", how to define it? Thank you
- General electric power on the four remote, remote, telemetry, remote control, remote control, and now there is more than one remote viewing. Remote signal is generally refers to the opening and closing state of each switch, remote measurement is the voltage, current, temperature, etc..
- Q: How to handle the qualification test, what kind of power equipment
- Acceptance; staff review the material you submitted to meet the requirements, may be 10 working days.(three) after acceptance, on-site verification. Staff to review your outfit team.
- Q: In order to obtain the qualification test of power equipment, the company needs to have a hard condition
- The provincial electricity supervisor application; can only apply for five (10KV and below) or level Four (35KV and below) qualification, the first level of qualification can only apply for the first four to rise
- Q: For example, EPS emergency power supply and so on, as well as those used in public emergencies.
- High / low voltage switchgear, power distribution cabinets, industrial ovens, constant temperature and humidity test box, ovens, air curtain machine (invisible door), inductive automatic door, air conditioning and industrial fans, NELL thyristor module, thyristor, single / three-phase bridge rectifier, fast recovery module
- Q: Definition of power equipment defects
- Emergency defectEquipment or facilities directly threaten the safe operation and the need to deal with, at any time may cause equipment damage, personal injury, large area blackout,Fire accident.Major defectsSerious threat to the human body, power grid and equipment, but also to adhere to the operation, not timely treatment may cause accidents.General defect
- Q: What are the two devices in the power system
- Connect the two device circuit, called the two line. In the two line of DC is generally used for communication detection equipment, such as PABX, PDH, MUX, generally for 48V DC power supply, AC line for AC equipment use
- Q: What is the redundancy of electrical equipment
- Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
- Q: The state of power system equipment is divided into four states
- (4) maintenance status. Circuit breaker and isolating switch device in the open position, the circuit breaker can be divided, and the control switch, fuse (or switch) switch maintenance should be off line and on both sides of the grounding switch (or installed ground), and hung signs work.
