Product Description:

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.

Solution of Large-scale Ground PV Power Station System

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 is the meaning of the high - voltage high - voltage device in power system
High voltage means high voltage, similar to the above. Alternating current has active power and reactive power, the frequency response is the balance of active power, and the voltage response is reactive power balance
Q:What is the LCP cabinet of electric power equipment
Junction box is a collection of all kinds of lines, equivalent to a transit station, the scene and control room may have.Electronic control box instruments and electrical appliances may be used.
Q:Power equipment are used, can help to divide some of the details
3 from the degree of importance can be divided intoCore equipment and auxiliary equipment4 from the price can be divided intoLarge valuable equipment, general equipmentPower plant and substation electrical equipment is divided into primary equipment and two equipment. A device (also known as the main equipment) is the main component of the power system, it is the direct production, electricity transmission and distribution equipment, including power generators, power transformers, circuit breaker, isolating switch, power bus, power cables and transmission lines. The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer. The primary equipment and its connected circuit is called primary circuit. Two equipment in accordance with certain rules to connect to achieve some technical requirements of the electrical circuit called the two circuit.Relay protection and safety automatic device, dispatching automation and communication system are the two systems.
Q:What is the double name of power equipment?
Such as: 307DL. The device name is on the circuit breaker, numbered 307DL, together they should write off on the line: circuit breaker 307DL
Q:What is the power equipment network
Hello: * power equipment network license, refers to the equipment after a rigorous examination of the administrative departments of electric power, can be put into the power grid stability [], [], no adverse effects on the power grid [] reliable products. From the technical point of view, the detection of more projects, more stringent requirements, you can apply to the local power management department, the network testing, examination and approval procedures, qualified to participate in bidding operations.
Q:What is the definition of abnormal equipment, equipment failure, equipment failure, equipment accident
Fault: operation is not normal, simple inspection process can be restored in time,Such as the use of electric leakage, overload caused by leakage circuit breaker trip.
Q:Withstand voltage test, power equipment insulation unqualified reasons?
Voltage test, power equipment insulation failure may be due to: insulation deterioration. Such as transformer oil into the water, solid insulation moisture, insulation aging, etc., will lead to decreased insulation performance, in the pressure test may not be qualified.
Q:How to run a company that operates electric equipment
Look for people who want to use the electrical equipment, such as the operator of the power station,
Q:The relationship between primary equipment and two equipment in power system
The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer.
Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
That response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power, get rid of the accident or the narrow scope of the accident to
