As the emergency backup power supply after power failure, the diesel generator set is in standby state most of the time. Once power failure or mains failure occurs, the standby diesel generator set plays a crucial role. However, we often find that the performance of the diesel generator set has problems after the occurrence of power supply failure, which shows that many users do not pay enough attention to the knowledge of ac false load for the detection and maintenance of the diesel generator set.

In order to effectively avoid the occurrence of accidents, strengthen the daily detection and maintenance of diesel generator set, establish a perfect diesel generator set detection and maintenance procedures, regular standard maintenance of diesel generator set, detection and maintenance is particularly important. This paper will focus on the common technical problems in the process of power maintenance.

First of all, why do diesel generators detect and maintain ac false loads?

1. Test the diesel generator set

By dummy load testing diesel generator set maintenance with communication, can detect diesel generating sets of unbalanced load capacity, to ensure that the steady state voltage regulation, the frequency of the steady state regulation, frequency of the transient voltage regulation, voltage recovery time, the transient frequency regulation, frequency recovery time, diesel generating sets continue to run test.

2. Check the UPS

Output voltage unbalance, output voltage regulation accuracy, overload capacity, dynamic voltage transient range, mains battery switching time, backup time, bypass inverter switching time.

Secondly, the main function of the diesel generator set is to detect and maintain the AC false load

1. Query function

Query diesel generator set search abnormal records, query diesel generator set test data.

2. Online communication

The detector can be connected with the upper computer through RS232/RS485 interface.

3. intelligent control and data processing functions

(1) Data transfer: After the test, the collected data can be transferred to the U disk;

(2) Online monitoring of the electrical parameters of the tested equipment;

(3) Data processing software function: data processing software and detector matching use. Detection parameters can be set to analyze and deal with the electrical parameters, operating status and abnormal records detected by the detector; Intelligent query, display, print charts.

(4) Automatic detection can be realized by setting parameters of detection equipment.

4. parallel function

The same model of products can be parallel, the equipment is equipped with RS485 digital parallel interface, unified control by the host, record the detection process.

5. stop protection function

Diesel generator set inspection and maintenance with ac dummy load on the general ac dummy load, load box based on the increase of intelligent control system, can be lack of phase, over-voltage and under-voltage protection Settings, once the equipment detected parameters beyond the set parameters, the equipment will sound alarm, and automatic shutdown protection.
