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: What are the main interference sources of the two power system
- Power system electromagnetic environment consists of one or two devices, of which there are a variety of electromagnetic disturbance and interaction, the current electric power system is developing towards higher voltage, higher capacity, power network is more intensive and more complex systems, more advanced equipment to the direction of development, to guide electromagnetic disturbance of power system more serious and complicated. On the other hand, the advanced power systems using more advanced automation and other electronic and computer control, measurement, communication and protection system, and solid state electronic based advanced equipment and system tolerance electromagnetic disturbance ability is weaker, more susceptible to electromagnetic environment.
- Q: Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed
- Power installation qualification certificate: one, two, level threeLevel 1: mechanical and electrical equipment installation engineering contract one class or the transmission and substation engineering contract qualification of an independent legal person to build more than 220 thousand volt classTwo level: mechanical and electrical equipment installation engineering contract two class or transmission and substation engineering contract qualification of independent legal person (220kV and below the transmission line, the construction of the substation) twoThree level: mechanical and electrical equipment installation engineering professional contract three level or transmission and substation engineering professional contract level three qualification of independent legal person (110kV and below transmission line, substation (room) construction)
- Q: What are the lightning protection measures of power system
- Use of cables in overhead line terminations (absorbing lightning waves). Arrester installed on overhead line terminal. Use of devices to prevent the operation of over-voltage as the backup protection of atmospheric overvoltage. To reduce the grounding resistance of tower.Improve the insulation level of the system. Wait。
- Q: Electric power automation equipment
- Construction and transformation of rural power grids, power plants, power plants, environmental protection, automatic control and integrated automation of nuclear power plants, technical management, etc..
- Q: What is the good rate of equipment determined by the rating of substation equipment
- The "system" can easily calculate the depreciation and repair costs of fixed assets in order to determine the economic life of the equipment, the best time to update. As a result of the "system" many functions of the set, so that enterprises can accurately grasp the technical status of the equipment, so as to determine the technical life of the equipment is very useful.
- Q: 1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?
- The common measurement and control cabinet are generally some common control signals such as AC / DC screen, knife position, device power loss and telemetry some voltage and current value, there are no specific remote control, measurement and control device of equipment access to public control
- Q: How to handle the qualification test, what kind of power equipment
- (a) legal person qualification and perfect organization; (two) the registered capital and net assets of 60 million yuan; (three) the last 3 years to bear the following first items listed, third project and second sub items listed in any one project, and the project quality: above 1 thousand and 330 volts voltage substation 2 or 220 thousand volt substation 5; more than 2 thousand and 330 volt overhead lines 300 kilometers or 220 thousand volt overhead line of 500 kilometers; more than 3 thousand and 220 volt cable line 80 kilometers or 100 meters above the level crossing tower crossing project 1.
- Q: How long has the power of power electronic equipment delivered water
- ; equipment (mainly separator population) and pipeline (mainly elbow) wear faster, if the design, construction or improper operation, is easy to cause material deposition, so that the conveying jam, interrupt; transportation should not be high humidity, viscous or easily broken material etc..
- Q: Electric power equipment start-up and commissioning of the project there is a difference?
- After a single commissioning, and then linkage test, after the test, such as no-load, put into operation in the above steps are completed, the test is no problem, start running with load.
- Q: The two devices of the power system have those
- Internal equipment:1, measuring meter, such as voltmeter, ammeter, power meter, electric energy meter for measuring electrical parameters in the circuit.2, insulation monitoring device.3, control and signal device.
