Designing small and medium-capacity diesel generator sets includes the following main stages: 1. Requirements Definition: It’s necessary to determine the required capacity of the generator set, its purpose (backup or primary power supply), operating time, working conditions (indoor or outdoor), noise and emissions requirements, and other relevant factors. 2. Selecting the Diesel Engine: Based on the required capacity and operating conditions, an appropriate diesel engine is selected. It must have sufficient power and reliability to operate continuously as needed without interruption. 3. Choosing the Generator: The generator must match the required capacity of the setup and provide stable voltage and frequency. Noise and emission standards also need to be considered. 4. Installation and Connection: The generator and diesel engine are installed on a designated platform or in a room equipped with proper ventilation. The generator is then connected to the power grid or system it’s intended to support. 5. Testing and Adjustment: After installation and connection, the generator set undergoes testing and fine-tuning. This includes verifying the functionality of all components, voltage and frequency stability, as well as compliance with emissions and noise standards. 6. Maintenance and Regular Servicing: The diesel generator set must be regularly serviced to ensure reliable operation and extend its lifespan. This includes oil and filter changes, cooling system cleaning, and other maintenance activities. Designing small and medium-capacity diesel generator sets requires expertise in electrical and mechanical engineering, as well as an understanding of power system requirements and operational conditions. The result should be a reliable, efficient, and environmentally compliant generator set capable of providing continuous power supply.

Preparing documentations for diesel electric station
Preparation of documentation for a diesel power station includes the following stages: 1. Information Gathering: All necessary information about the diesel power station must be collected, including its specifications, technical description, operating principles, components and equipment, power supply requirements, and more. 2. Specification Compilation: Based on the collected information, a specification for the diesel power station must be compiled, covering its main characteristics, data on components and equipment, as well as applicable standards and regulations. 3. Technical Documentation Development: Based on the specification, technical documentation is created, including installation, configuration, and operating instructions for the diesel power station, electrical diagrams, user manuals, and other required documents. 4. Review and Editing: After creating the documentation, it must be reviewed and edited for errors, inaccuracies, and compliance with requirements. 5. Formatting: The final version of the documentation must be formatted according to established standards and requirements, including proper layout of titles, page numbers, tables, illustrations, and more. 6. Distribution: The final version of the documentation should be distributed among interested parties, whether suppliers, contractors, or users of the diesel power station. It is essential to note that each diesel power station may have unique characteristics and documentation requirements, so specific customer or regulatory needs should be considered during the preparation process.

Calculation of the power of electrical installations
For calculating the power capacity of a diesel generator set, the following parameters need to be considered: 1. Load: Determine the total load you plan to connect to the generator, considering both continuous and peak loads, usually measured in kilowatts (kW). 2. Power Factor: The power factor (cos(φ)) represents the ratio of active power (kW) to apparent power (kVA). Diesel generators generally use a power factor between 0.8 and 1.0. 3. Power Reserve: It is recommended to add a power reserve to the required load to ensure reliable generator operation in the event of load growth or additional loads, usually 10-20% of the required load. 4. Generator Efficiency: Find out the efficiency of the diesel generator, typically expressed as a percentage. This will help calculate the active power (kW) the generator can provide. Considering all these parameters, you can calculate the active power (kW) of the diesel generator set using the formula: Active Power (kW) = Load (kW) / (Power Factor * Generator Efficiency * Power Reserve). For example, if the load is 100 kW, the power factor is 0.8, generator efficiency is 90%, and power reserve is 10%, the calculation will be as follows: Active Power (kW) = 100 / (0.8 * 0.9 * 1.1) = 129 kW. Thus, the diesel generator set should have a power capacity of at least 129 kW to reliably cover the specified load, considering the power factor, generator efficiency, and power reserve.

Construction of diesel generator sites
Construction of sites for diesel generator sets (DGS) refers to creating special sites or foundations for installing DGS. These sites are designed for the installation and operation of DGS and include several key stages: Site Preparation: This includes clearing the site of vegetation, earthworks, leveling the surface, and ensuring proper drainage. Foundation Design and Construction: Depending on local conditions and reliability requirements, a specialized foundation or pad for the DGS may need to be built. This could be a concrete foundation or slab set on-site, as well as reinforced supports to bear the generator's weight. Safety Systems Installation: This involves securing the site, preventing unauthorized access, and providing ventilation and fire protection systems. Utility Connections: This includes setting up necessary connections such as electrical cables, fuel pipelines, ventilation systems, and drainage channels to ensure proper DGS operation. Installation and Mounting of DGS: After completing the preparatory work, the diesel generator set is installed and mounted on the specially prepared site. Testing and Commissioning: After installation, all DGS systems are checked, adjusted, and started to ensure correct operation and safety. Constructing sites for DGS requires specialized knowledge and expertise in construction, electrical engineering, and mechanics, as well as adherence to relevant safety standards and regulations.

Automation and fire safety system
The automation and fire safety system of diesel generator sets (DGS) is designed to ensure reliable generator operation and prevent fires and emergency situations. It includes several components and functions: 1. Automatic Control and Monitoring System (ACMS): Responsible for the automatic operation of the generator, monitoring its parameters (voltage, current, frequency, etc.), and protecting against emergency situations (e.g., overload, short circuit). The ACMS ensures generator stability and adapts to required power consumption. 2. Engine Temperature and Pressure Monitoring System: Monitors engine operation, including temperature, oil pressure, and coolant levels. If limits are exceeded, the system automatically shuts down the generator to prevent potential emergency situations. 3. Fire Safety System: Includes smoke detectors, temperature sensors, and other devices to detect potential fire sources. Upon detection, the system automatically activates firefighting equipment, such as extinguishers, fire hydrants, or an automatic fire suppression system. 4. Backup Power: In the event of a primary power source failure, the system automatically switches the generator to backup mode. This ensures uninterrupted operation of electrical installations and prevents emergencies. 5. Monitoring and Control System: Allows the operator to remotely monitor and control the DGS operation via a computer or mobile device. The operator can check the generator's performance, receive notifications of potential failures and emergencies, and configure system parameters. All these components and functions of the DGS automation and fire safety system are intended to ensure safe, reliable, and efficient generator operation and prevent potential emergency situations.
