Environmental challenges of the coal plant and its impact on the power system
- 1. **Dust and suspended particles:** The process of grinding coconut shell or wood produces large amounts of powder and fine particles. If these particles penetrate into electrical panels, electric motors, and sensors, they will cause a connection, improper cooling, and ultimately damage the parts.
- 2. **Severe vibrations:** Hydraulic presses and mills have high mechanical vibrations. Continuous vibration can loosen electrical connections, break motor bases, and damage terminals.
- 3. **Temperature and humidity fluctuations:** Carbonizing and drying processes produce a lot of heat. Heat can destroy the insulation of the wires and disrupt the operation of the electronic parts of the steering wheel. 4. **Urban electricity fluctuations:** In many areas of Tehran, voltage fluctuations and voltage drops during heavy engine starts are common. Without proper protection systems, these fluctuations can burn out control boards and motor drives.
Key components of the electrical system of coal machinery
1. Main and distribution panel (Power Distribution)
- * **Engineering note:** The use of automatic switches with a suitable cut-off curve for induction motors (which have a high starting current) is necessary to avoid disconnection and connection for no reason. be.
2. Central control panel
- * **PLC (Programmable Logical Controller):** Using reliable brand PLCs (such as Siemens or Delta) for automatic process management.
- * **HMI (Human-Machine Interface):** Touch screens to graphically display the status of devices, temperature, pressure and speed to the operator.
- * **Variable Frequency Drives (VFD):** For precise control of motor speed Mills and conveyors. These parts not only reduce energy consumption, but also reduce mechanical wear and tear.
3. Electric Motors
- * **Branding:** Use of reputable high-efficiency brand motors (IE3 or higher) that have more optimal power consumption.
- * **Cooling system:** Motors with a strong internal fan or external cooling system to work in hot environments.
4. Industrial wiring and cabling
5. Safety systems and sensors
- * **Limit switches:** to detect the position of hydraulic cylinders and conveyors.
- * **Temperature and pressure sensors:** To monitor the condition of furnaces and hydraulic pumps at the moment.
- * **E-Stop buttons:** Installed in strategic points of the workshop for immediate stopping in times Danger.
Why is electricity fluctuations in Tehran a serious threat?
Tehran, as a densely populated metropolis, faces challenges in the stability of the electricity network. Pressure on the network, especially during the peak hours of summer or winter, can lead to voltage drop or sudden increase in voltage (Surge).
- * **Voltage drop:** causes electric motors to draw more current from the network to provide the necessary torque. This will cause the motor winding to heat up and burn in a short time.
- * **Voltage fluctuations:** Can burn sensitive electronic boards in the steering panel and motor drives.
The solution to this problem is to use **industrial stabilizers** and **voltage protection relays** in the main electrical panel. Also, the design of the system prevents accidents by considering the appropriate safety factor for wires and keys.

Comparison of traditional electrical system with modern intelligent system
| Feature | Traditional electrical system Sorena intelligent system of Pars car |
| :--- | :--- | :--- |
| **process control** | Handy and complicated Automatic with PLC and HMI |
| **Protection against fluctuation** | Weak or no system Has oscillator and stabilizer keys |
| **Troubleshooting** | Difficult and time consuming Display the error code on the screen and the Farsi guide |
| **energy consumption** | higher (no speed control) | Optimum (use of variable frequency drives) |
| **Useful life of the device** | less (high depreciation) | More (exact control of pressure and speed) |
| **job security** | Dependent on the operator's experience Standardization of the process and reduction of human error |
Tips for preventive maintenance and repairs for the electrical system
To ensure the correct operation of the **electrical system of coal machinery in Tehran**, it is necessary to observe the following points:
- * **Regular cleaning of the electrical panel:** Coal dust can accumulate in the electrical panel. Clean the electrical panel with compressed air every month (with the power off).
- * **Connection check:** Every 3 months, tighten the wire connections at the terminals. The vibration of the devices can cause them to loosen.
- * **Motor temperature monitoring:** Check the body temperature of electric motors using a laser thermometer. Abnormal heat is a sign of trouble.
- * **Periodic inspection of cables:** Check cables that are subject to wear or contact with hot surfaces to ensure that their insulation is not damaged.
