2. Isiqondiso sesayensi
Frequency conversion technology is one of the important means of mechanical energy-saving design and renovation in today's society. Through frequency conversion energy-saving technology, a large amount of electricity energy can be saved. Variable frequency regulation technology plays an important role in the power system of coal mine equipment, which can reduce the operational difficulty of the power system and improve work efficiency. The power system structure of coal mining equipment is complex, and the difficulty of operation is also very high. There are huge safety hazards, and improper operation can lead to safety accidents and serious consequences. After adopting frequency conversion regulation technology in the power system of coal mining enterprises, this situation can be changed to a certain extent, reducing the operational difficulty of the power system and improving work efficiency. At the same time, the use of frequency conversion regulation technology can provide scientific guidance and standardized operation for mining operations, providing guarantees for the safety production of coal mines.
3、 Energy saving methods
1. Reduce energy consumption of reactive power
Variable frequency regulation technology is adopted in coal mine machinery equipment to improve the reactive power of the equipment and reduce the energy consumption of reactive power. The reactive power of coal mining machinery equipment needs to be appropriate. Once the reactive power generated by the equipment is too high, it will cause the equipment to heat up and damage the wiring of the equipment. The reactive power of coal mining machinery equipment can also affect the active power of the power system. Once the factor of reactive power decreases, the useful power of the power system will also decrease accordingly. If such a phenomenon occurs, it will increase the reactive energy consumption, thereby affecting the production efficiency of the equipment and increasing the overall energy consumption of the equipment. By using frequency conversion regulation technology, the consumption of reactive power can be reduced to a certain extent through the regulation of the frequency converter, thereby increasing the efficiency of useful power work and providing overall utilization of equipment electrical energy, achieving energy-saving effects.
2. Change the startup mode
Traditional coal mining machinery and equipment use old-fashioned electric motors, which are started before coal mining operations begin. The starting method is usually hard starting, which can have a huge impact on the power system, affecting its normal operation and causing damage to the power system. During the process of starting the electric motor, if the power system requires a large amount of electricity, the motor will be affected by strong currents and vibrations, causing damage to the valves and baffles of the motor, as well as affecting related mechanical equipment. After applying frequency conversion regulation technology in the coal mine power system, the frequency converter will adjust the relevant current according to the actual needs of the motor, gradually increasing it from zero, which will effectively control the starting current of the engine. This starting method can reduce power consumption, improve energy utilization, protect the valves and baffles of the generator, and extend the service life of the equipment.
3. Variable frequency energy-saving
The application of frequency conversion regulation technology in coal mining machinery equipment can achieve energy-saving effects. Because the operating power of coal mining machinery and equipment is constant, when the operating load of the equipment cannot meet the requirements, the consumption of active power will increase, resulting in energy waste. In the past, in order to regulate the energy required for the operation of the electric motor, it was generally necessary to adjust the energy by changing the baffle and valve. During the adjustment process, energy was wasted and a lot of unnecessary energy was lost. Nowadays, many coal mining enterprises adopt variable frequency regulation technology for their mechanical equipment, which can flexibly adjust the required energy and real-time regulate the energy required for the operation of coal mining equipment. According to the operating status of the motor at that time, the corresponding energy can be adjusted to avoid energy waste, thus saving energy and improving energy utilization efficiency.
