Generator set selection

With the rapid development of science and technology and the enhanced environmental awareness among the public, there is an increasing demand for functionality and diverse application conditions. As a result, traditional diesel generator sets and their associated products (hereinafter referred to as "sets") have been infused with high-tech and environmentally friendly connotations in modern times. This selection specification aims to provide a comprehensive solution for modern set selection and usage, seeking to achieve a balance between performance and cost, high reliability, and environmental protection. The main features of the sets include a full-featured high-integration control, which evolves from the traditional control of simple functional components to a modular high-integration control utilizing advanced high-tech achievements. On one hand, it enhances control functions such as set protection, display of operating parameters, historical records, remote computer monitoring, and optimized load management; on the other hand, it achieves less or even touchless control, improving operational reliability. Environmental-friendly low-noise operation can be achieved by adding soundproof enclosures or noise reduction devices in the machine room. Exhaust purification units can be added as necessary to achieve cleaner emissions. Rapid mobile emergency power supply is provided by mobile power stations on vehicles, with trailer-mounted power stations capable of meeting the needs for quick deployment. Standard sets are widely used in general locations where installation within machine rooms is required. Sets are mainly composed of diesel engines, generators, control systems, bases, vibration dampers, cooling systems, fuel supply systems, and output protection switches. Silent-type sets are used in outdoor locations with specific noise requirements. They are mainly composed of standard sets, silent protective enclosures, and exhaust systems. Sets for special purposes can be equipped with trailers or customized mobile power generators.

Power matching and on-site application conditions for power correction are the core content of equipment selection. The principle is to meet the usage requirements with minimal investment. Firstly, it is essential to clearly understand the definitions of various power types, analyze the operational characteristics of the equipment, and determine the power conditions. Then, based on the on-site conditions of the equipment and the characteristics of the load, calculate, correct, and determine the required output power of the equipment.ISO 8528-1:1993 and GB/T 2820.1-1997 specify the application, ratings, and performance of AC generator sets. This standard categorizes the output power of AC generator sets into three types: Limited Time Performance (LTP), Prime Power (PRP), and Continuous Power (COP). Additionally, it outlines the field conditions for operation: field conditions are determined by the user. In the absence of known field conditions and specific provisions, the following rated field conditions should be applied: Atmospheric Pressure: 89.9 kPa (or altitude of 1000m), Environmental Temperature: 313 K (40°C), Relative Humidity: 60%. Field conditions for ISO power: Atmospheric Pressure: 100 kPa (or altitude of 300m), Environmental Temperature: 298 K (25°C), Relative Humidity: 30%.

Continuous Power (COP) refers to the power existing within a certain constant power sequence, which may operate for unlimited hours per year under the specified maintenance cycle and environmental conditions. It is equivalent to the Continuous Power defined in national and ISO standards. Generally applicable to continuous operating conditions with minimal load changes, such as power stations or grid-connected operations.

Power within a variable power sequence, where the running hours per year are unrestricted between scheduled maintenance cycles and under specified environmental conditions, is equivalent to the Basic Power (PRP) as defined in national and ISO standards. Generally applicable to industrial and mining operations with minimal load variations and frequent operation.

3 standby power generating sets can operate continuously for 300 hours between scheduled maintenance cycles and under specified environmental conditions, with an additional 500 working hours of power per year. This is equivalent to the Limited Time Power (LTP) as defined in national and ISO standards. Generally applicable to emergency conditions with significant load variations in communication, building, etc.

When selecting a generator set, what aspects should we consider? Firstly, a high-quality product is crucial. Secondly, generators of different powers and models should be used in suitable environments to achieve their effective power generation capacity.
Due to the actual output power of generators, pumps, and motors being affected by factors such as altitude, temperature, and environmental humidity. As altitude, temperature, and environmental humidity increase, the power output of generators will decrease by varying proportions. Please take this into account when calculating the generator's operating power and proceed with the purchase to avoid insufficient power usage.
Similarly, due to the varying types of appliances, the starting current can differ significantly, thus requiring different power generator capacities. Therefore, when selecting products, users should first calculate the power requirements of the high-capacity generators needed for normal operation. Refer to the following specifics:
Resistive appliances (such as bulbs, electric stoves) have a power ratio of 1:1.
*Electrical感性appliances (such as lamps) have a power ratio of 1:2.
Power ratio of electric tools and electric fans is 1:3 (e.g., angle grinders).
Air compressors, woodworking planers, machine tools, and milking machine power ratio1:4 (For example, a 1KW air compressor requires a 4KW generator).
Of course, generators, pumps, and power units must also follow certain operational procedures. For instance, engine oil should be filled to the correct level. For machines without an oil level indicator, fill until the oil starts to溢出 (when the machine is lying flat). For machines with an oil level indicator, fill the engine oil strictly according to the instructions. Overfilling the engine oil can cause black smoke and out-of-control operation, while underfilling can lead to engine seizure. Do not add engine oil to the oil tank while the machine is running to avoid danger. Similarly, do not add fuel to the oil tank while the machine is operating to prevent the machine from catching fire and being damaged. On the first consecutive use20 hours or 1 month of storage requires oil change to prevent excessive machine wear. Afterward, change the oil after every consecutive 100 hours of use or 3 months of storage, as per the machine's user manual. When the temperature is below 0°C, the diesel engine must use diesel with a grade corresponding to the ambient temperature of the equipment. Otherwise, waxing of the diesel will prevent the generator from starting normally. Similarly, when the temperature is below 0°C, the correct oil type for the ambient temperature must be used to avoid damage to the generator's power output. Operators must carefully read the user manual before use and must perform checks as required by the manual.
