5. Common FAQ

Q1: What is the practical difference between prime power and standby power of YC6TH1320-D31 generator set?

The 800kW/1000kVA prime power is continuous rated power, which supports long-term full-load stable operation and is suitable for daily off-grid main power supply and long-time continuous load operation. The 880kW/1100kVA standby power is emergency peak power, only used for short-time power supply when the municipal grid fails. According to industry specifications, the cumulative annual use time of standby power shall not exceed 500 hours, and long-term full-load operation is prohibited. Frequent overuse of standby power will accelerate engine mechanical wear, increase equipment failure rate and significantly shorten the overall service life of the generator set.

Q2: Why is brushless self-excited alternator the preferred configuration for this large-power Yuchai generator set?

Different from traditional brushed alternators, the brushless self-excited structure cancels carbon brushes and slip ring friction components, fundamentally eliminating mechanical wear, electric spark and electromagnetic interference during high-power operation. For 1000kVA large-power units, brushed structures are prone to high-temperature aging and frequent failures under long-term heavy load, while brushless alternators have lower failure rate and higher operational safety. Meanwhile, it removes the need for regular carbon brush inspection and replacement, only requiring daily dust cleaning and oil circuit inspection, which greatly reduces long-term operation and maintenance costs for users.

Q3: How to effectively control fuel consumption of YC6TH1320-D31 800kW diesel generator set in daily operation?

First, avoid long-term no-load idle and light-load operation, and keep the unit operating load stable at 60%-80% of rated power, which is the most energy-efficient working range for this TH series large-power unit. Second, regularly replace air filters, diesel filters and oil filters to ensure sufficient air intake and full fuel combustion of the twin-turbo system. Third, regularly check the closed-cycle water cooling system and fuel injection system to avoid power attenuation and increased fuel consumption caused by poor heat dissipation and abnormal fuel supply. In addition, using qualified standard diesel oil and special lubricating oil can effectively optimize combustion efficiency and reduce comprehensive operating fuel consumption.
