COMLER High Voltage Generator Set Power Supply System (Engineer XNL)
The COMLER high-voltage generator set complies with the provisions of the national standard 《GB/T 2820 - RECIPROCATING INTERNAL COMBUSTION ENGINE DRIVEN AC GENERATOR SET》 《IEC 60034 - ROTATING GENERATOR》, 《GB/T 31038 - GENERAL TECHNICAL CONDITIONS FOR HIGH VOLTAGE DIESEL GENERATOR SETS》《YD/T 2888 - COMMUNICATION HIGH-VOLTAGE GENERATOR SETS》.The fuel consists of be diesel, heavy oil and gas, and the voltage levels can be 6300V, 10500V, 15000V.
The COMLER high-voltage generator set has high precision voltage regulation , excellent dynamic performance, small voltage waveform distortion, high efficiency, compact structure, easy maintenance, reliable operation, long service life, and good economic performance. Due to the high output voltage and low output current of the unit, along with the characteristic of low power loss during power transmission, so that it is highly suitable for long-distance power transmission. The high-voltage power supply system can directly connect to high-voltage loads, save large sum of investment costs for power supply and distribution system equipment, and is more convenient to use.
Power Supply Characteristic
The COMLER series of high-voltage power generation units can be operated either as a single unit for power supply, or as multiple units forming an independent power grid (parallel operation) to supply power to the load, or as a single unit or multiple units connected through the parallel grid connection management system to be integrated with the mains power supply to form a power grid for supplying power to the load.
Application
The COMLER high-voltage power generator set have been widely used, especially in applications where the bigger capacity and the long transmission distance. The high-voltage diesel power generator set has these obvious advantages such as large capacity, long-distance power supply, strong reliability, and reasonable structure for the power distribution system. The high-voltage diesel power generator set has been widely used in more fields such as mining, metallurgy, data centers, ports, and airports. The intelligent control system saves energy for parallel connection and large unnecessary investments for power supply and distribution systems. Especially the characteristic of high voltage and low current determines the advantage of long-distance transmission of high-voltage generators.
Data Centre Application
The COMLER high-voltage power generator set is the key technical solution for large and super-large data centers to meet the demand for large-capacity backup power. By means of increasing the voltage level and effectively overcomes the problems of high transmission loss, huge cable usage, excessive space occupation, and complex parallel connection for low-voltage systems with high power operation. Although its initial investment and system complexity are relatively high, and the operation and maintenance requirements are more professional, the long-term operational efficiency (low loss), space savings, and system architecture simplification (compared to massive low-voltage parallel connections) make it irreplaceable in meeting the high power density, high reliability, and high energy efficiency requirements of modern data centers. When choosing a high-voltage solution, a comprehensive technical and economic comparison (TCO analysis) must be conducted, and the design, equipment selection, installation quality, and professional operation and maintenance management of the high-voltage system must be given high attention.

4.PT cabinet (option): This is a voltage transformer cabinet. In high-voltage power distribution, due to the extremely high voltage, it cannot be directly connected to secondary equipment. Therefore, a voltage transformer is needed for conversion. Generally, 10KV voltage is converted to 100V or 220V, and then connected to protection devices, metering devices and etc. |
