product requirements and challenges of petrochemical diesel generator sets

Because of the particularity of petrochemical industry, high-performance diesel generator sets have to be equipped for environmental and efficiency considerations. Kaichen Power specially developed this kind of special generator set for petrochemical industry, which has short response time, rapid start-up and stable current and voltage frequency, and can provide continuous and stable power output for owners in case of power failure.

Generator sets for petrochemical industry generally include mobile diesel generators and fixed diesel generators. According to functions: ordinary generator set, automatic generator set, monitoring generator set, automatic switching generator set and automatic parallel generator set. According to the structure: open frame generator set, box generator set and mobile generator set. Box-type generator set can be divided into: box-type rain-proof box generator set, low-noise generator set, ultra-quiet generator set and container power station. Mobile generator sets can be divided into trailer mobile diesel generator sets and vehicle-mounted mobile diesel generator sets.

Although there is grid power supply in the oilfield, the supply is abnormal, and the power supply is often stopped due to season, bad weather or line failure, and the performance is stable, which supports the normal operation of the oilfield.

1. Serial and parallel functions

Serial machine backup function: it can cooperate with ATS to realize the automatic switching function between commercial power and diesel generator set or the dual standby switching function between two diesel generator sets.

Parallel expansion function: two or more three-phase units with the same specifications and models can run stably in parallel within the range of (20-100) rated power under the rated power factor. In order to improve the reasonable distribution accuracy of active power and reactive power and the stability of operation, the diesel engine governor in the unit is required to have a device for adjusting the steady-state speed within the range of (2-5). The voltage regulating device in the control box (screen) can adjust the steady-state voltage regulation rate in the range of 5.

2. Working conditions

It can run below 3000 meters above sea level;

The lower limit of ambient temperature is-15 C and the upper limit is 40 C. Other environmental units can be selected.

3, stable performance and strong reliability

The average time between failures of the unit is not less than 2000 hours.

4, convenient refueling facilities and protective measures.

The unit is equipped with an external refueling system and equipped with a locking function;

Usually, a large oil tank is needed, which can meet the requirements of 12-24 hours operation.

solutions

The generator set with excellent and stable performance is designed with low noise and equipped with PLC-5220 control system with AMF function. By connecting with ATS, it is ensured that the alternative power supply system can provide power immediately once the main power supply is cut off.

advantages

Provide a complete set of products and solutions, reduce the user's requirements for mastering technology, and make the use and maintenance of the unit easier;

The control system has AMF function, which can be started automatically, and has many automatic stop and alarm functions under monitoring;

Optional ATS, small units can choose built-in ATS;

Ultra-low noise power generation to meet the needs of daily life;

Stable performance, the average time between failures of the unit is not less than 2000 hours;

The unit is small in size, and some devices can be selected to meet the operation requirements in cold areas and high temperature areas;

The special needs of some customers can be customized for design and development.
