Generator set selection

With the rapid development of science and technology and the enhanced environmental awareness among the public, the increasing demand for functionality and the varied application conditions have infused traditional diesel generator sets and their accessories (hereinafter referred to as the set) with high-tech and eco-friendly connotations in modern times. This selection specification aims to provide an integrated solution for the selection and use of modern sets, seeking to achieve a balance between performance and cost, high reliability in operation, and environmental protection. The main features of the set include a comprehensive, high-integrated control system, which has evolved from the traditional control of separate components with simple functions to a modular, high-integrated control utilizing modern high-tech achievements. On one hand, it enhances control functions, including protection of the set, display of operating parameters, historical records, remote computer monitoring, and optimized load management; on the other hand, it achieves less contact or contactless control to improve operational reliability. Eco-friendly low-noise operation is achieved through the addition of noise-reducing enclosures or noise reduction devices in the machine room. Exhaust purifiers can be installed as needed to achieve cleaner emissions. Rapid mobile emergency power supply is provided by mobile power stations mounted on vehicles, with trailer-mounted power stations capable of meeting the needs for rapid mobile emergency power. Standard sets are widely used in general installations within machine rooms. The set is 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 special 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 generation vehicles, etc.

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 regulates 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%.

1. Continuous power refers to the power within a certain constant power sequence that may be operated for an unlimited number of hours per year, between scheduled maintenance cycles and under specified environmental conditions. This is equivalent to the Continuous Power (COP) as defined in national and ISO standards. It is generally suitable for continuous operating conditions with minimal load variations, such as power stations or grid-connected applications.

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

3 standby power generators can operate continuously for 300 hours within the specified maintenance cycle and under the specified environmental conditions, with an additional 500 working hours of power per year. This is equivalent to the Limited Time Power (LTP) as per national and ISO standards. Generally applicable to emergency conditions with significant load fluctuations, such as in communication and building facilities.

When selecting generator sets, what aspects should we consider? Firstly, a high-quality product is crucial. Secondly, different generators with varying power and models should be used in suitable environments to achieve the effective power output of the generator.
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 greatly, leading to different power requirements for generators. Therefore, when selecting products, users should first calculate the power output of generators that can meet normal usage. Please 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, water pumps, and power sources must also follow a certain operational procedure during use. For example, engine oil should be filled to the correct level. For machines without an oil level indicator, fill until the oil starts to leak out (when the machine is lying flat). For machines with an oil level indicator, follow the instructions in the manual strictly for adding engine oil. Overfilling can lead to black smoke and out-of-control operation, while underfilling may cause the engine to seize. Do not add engine oil to the oil pan while the machine is running to avoid danger. Also, never add fuel to the oil tank while the machine is running to prevent the machine from catching fire and being damaged. During the first consecutive useAfter 20 hours or 1 month of storage, engine oil must be changed to prevent excessive wear on the machine. Subsequently, replace the oil after every 100 continuous hours of use or every 3 months of storage (refer to the machine's instruction manual for details). When the temperature is below 0°C, diesel engines must use diesel oil with a grade corresponding to the ambient temperature of the equipment; otherwise, waxing of the diesel may prevent the generator from starting normally. Similarly, when the temperature is below 0°C, the correct type of engine oil must be used, matching the ambient temperature of the equipment, to avoid damage to the generator's power output. Operators must carefully read the instruction manual before use and perform checks as required by the manual.
