Realize efficient operation of power plants

Now, power generation companies are conducting business in a fiercely competitive market. From market liberalization

Business operation pressure and continuously rising fuel costs require all power generation companies to seek

The most effective way to convert a larger proportion of fuel energy into electricity suitable for sale. change

The heat consumption rate of power plants is becoming increasingly important.

Thermal power plants typically consume 5% to 10% of the electricity generated. Due to the installation of anti pollution devices

Be prepared, this proportion has been continuously increasing in recent years.

The process of motor-driven typically consumes 80% of this electricity. Install frequency converter

(VSD) can improve the heat rate by increasing the efficiency of these processes.

Operational flexibility is key to ensuring economic production during periods of low and peak demand.

Improving heat consumption rate and output power can enhance profitability and quickly generate investment returns.

Investing in frequency converters can improve the availability and flexibility of power plants by enhancing process control

Activate, reduce emissions, and lower maintenance costs.

Flow and pressure control

conserve energy ,reduce emissions

The difference between gas consumption and water consumption is significant within a day. In this regard, it is necessary to consider the fan

Due to the fact that pumps and fans usually operate at partial loads, they are controlled by using frequency converters

Continuous control of processes and equipment such as pumps.

Rotational speed can greatly save energy. A slight decrease in rotational speed can significantly reduce energy consumption. Pump or

When the fan runs at half the speed, the energy consumption is only one eighth of that when it runs at full speed.

Comparison between Mechanical Control and Electrical Control

The process driven by a pump or fan usually uses imported guide vanes, throttle valves, or hydraulic couplings

By using frequency converters to control centrifugal pumps and fans instead of throttling or damping

Perform mechanical control or use a frequency converter for electrical control.

Control can reduce energy costs by up to 50%. So, using a frequency converter can also help reduce

Reduce the emissions of nitrogen oxides and carbon dioxide.

It is impossible to achieve the process within the entire control range using a mechanical constant speed solution

Maximizing efficiency.

With the help of a frequency converter, the production volume can be changed by simply changing the motor speed. This can save

Reduce energy consumption, minimize carbon dioxide emissions, and minimize total operating costs. change

Frequency converters can achieve the highest efficiency, surpassing hydraulic couplings and other mechanical control systems.

Soft start

Using heavy-duty torque and/or high-quality inertia torque to accelerate the speed of motors, such as induced draft fans,

It will generate significant stress on the mechanical components of the power supply network and shaft system. Direct online starting power

The machine will result in a starting current six times the rated current. This will cause a voltage drop,

It is likely to cause interference to the process, especially in situations where the power supply network is relatively fragile

Below.

Soft starting through a frequency converter can bring significant benefits:

- Will not cause interference to the process due to voltage drop; Other electrical devices connected to the same bus

The gas equipment will not trip

- Will not generate excessive thermal or mechanical stress on the motor, thereby extending its service life

Start immediately without any delay in warm-up (according to the requirements of the steam turbine)

Stable start with controlled operation

The benefits of using a frequency converter

- High availability

- Achieve fast and precise process control under all conditions

- Reduce energy consumption

- Reduce emissions

- Soft starting capability can extend the service life of electromechanical equipment
