DEFINITION OF HIGH VOLTAGE GENERATOR

The high-voltage (HV) generator set is relatively speaking to the low-voltage (LV) generator set. The main difference is the voltages level. Generally, the low-voltage generator set refers to the voltage levels less than 1000V, such as 230V/400V(50Hz) and 270/480V(60Hz), which is commonly available in the generation market. For high-voltage (HV) generator sets, it refers to voltage levels more than 1000V, such as 3.3 kV, 6.3 kV & 10.5 kV (for 50Hz) and 3.3 kV, 4.16 kV, 6.6 kV & 13.8kV (for 60Hz).
 
The main purpose of High-voltage generator set is to meet the electricity demand of high voltage equipments, long-distance electricity transportation and high-power electrical load for parallel operation.
 
For high voltage (HV) genset, ETTES adopt world-famous engine brands such as Cummins, MAN, MWM, MTU, Perkins, Mitsubishi and CNPC 190 series., coupled with world top alternators brands such as Leroy-somer, Siemens and Stamford etc, the fuel can be diesel or gas (natural gas and biogas), with features of high intelligence, low noise, good starting capability at low temperature, long durability, little vibration easy operation and fully supporting functions and so on.

COMPOSITION OF ETTES HV GENERATION

For ETTES power HV generator units, the main composition includes engine (fuel can be diesel or gas, adopted brands like Cummins, MAN, MWM and MTU…), high-voltage alternator (adopted brands like Leroy Somer, Siemens…), high-voltage switch-gear cabinet, grounding resistance cabinet, PT cabinet, parallel cabinet (incoming cabinet), general outgoing cabinet, DC panels, outgoing cabinet for plant internal use though step-down transformer and centralized monitor & control system (SCADA) etc.
