The automatic control system is an important part of the diesel generator set. Its main functions mainly include automatic maintenance of ready-to-run status, automatic starting and loading, automatic shutdown, automatic paralleling and de-sequencing, automatic replenishment, unattended time, automatic protection, etc. In order to give users a more comprehensive understanding of diesel generator sets, Dingbo Power will introduce you in detail below, let’s take a look.
The composition of the automatic control system of diesel generator set.
1. Program control.
The automatic control system of diesel generator set is controlled according to the pre-designed operation sequence. The control signal only plays a discrete role, and the parameter is a switch value. The form of the control signal is usually taken from the result of several operational logic operations. For example, the start and stop of the unit belong to program control.
2. Analog control.
By measuring the actual value of the operating parameters of the equipment and comparing it with the set value, according to the deviation, the corresponding physical quantity of the equipment is adjusted to achieve control and adjustment.This kind of control signal works continuously, and the parameter is usually an analog quantity. It can also be converted into a discrete quantity of time by means of timing sampling, but no matter how large the deviation is, it should be adjusted continuously following the set value. For example, the adjustment of frequency and voltage is analog control.
3. Operation management control.
Operation management control refers to the operation of electric generator by invoking various automatic devices or corresponding procedures in order to achieve the purpose of safety control and economic operation in accordance with the requirements of various operating conditions and the actual needs of the load set manually.
Features of Diesel Generator Set Automation Control System.
1. Maintain the continuity and reliability of power supply.
The automatic control system can accurately and quickly adjust the operation of the diesel generator set. When the generator set is abnormal, the automatic control system can correctly judge and deal with it in time, and send out the corresponding alarm signal or emergency shutdown to avoid damage to the generator set. At the same time, it can also automatically start the standby generator set, shorten the power outage time of the grid, and ensure the continuity of power supply.
2. Improve power quality indicators and operating economy, and keep all electrical equipment in good working condition.Electrical equipment has high requirements on the frequency and voltage of electrical energy, and the allowable deviation range is very small. The automatic voltage regulator can keep the voltage constant and manipulate the speed regulator to adjust the frequency. Automated diesel power plants rely on automatic adjustment devices to complete the adjustment of frequency and useful power.
3. Speed up the control and operation process and improve the continuity and stability of the system. After the diesel power station is automated, the operating conditions can be changed in time to adapt to the system requirements, and the unit operation process can be carried out in a predetermined sequence without interruption, and its completion can be continuously monitored. Take the emergency start generator set as an example. If manual operation is adopted, it takes 5~7min at the fastest. If automatic control is adopted, it will usually start successfully in less than 10s and the power supply will be restored.
4. Reduce operators and improve working conditions. The environmental conditions during the operation of the computer room are quite harsh, which affects the health of the operators. The automatic control system of diesel generator sets has created conditions for unattended operation.
The above is an introduction to the composition and characteristics of the diesel generator set automation control system compiled by Dingbo Power for you. I hope it will be helpful to you.
