Power Quality and Power Supply Reliability in Control Systems

1. Power Quality

Power quality refers to whether the electrical power supply (in terms of voltage, frequency, waveform, etc.) meets the requirements for the proper operation of the control system.

Key indicators:

• Voltage Stability:
• Voltage should remain within ±10% of the rated value.
• Excessive voltage fluctuations can affect the operation of electronic components.
• Frequency Stability:
• Typically, a frequency of 50 Hz (with a ±0.5 Hz tolerance) is required.
• Frequency deviations can cause motor speed variations or sequence errors.
• Harmonic Content:
• Nonlinear loads (e.g., variable frequency drives, UPS systems) introduce harmonics that can interfere with communication and sensor signals.
• Harmonic filters or correction devices should be used.
• Voltage Transients and Surges:
• Caused by lightning strikes or motor switching.
• Surge protection devices (SPDs) can help mitigate the effects.
• Voltage Sags and Short Interruptions:
• May cause system restarts or malfunctions.
• Solutions include uninterruptible power supplies (UPS) or redundant power systems.
• 
  

2. Power Supply Reliability

Power supply reliability refers to the ability of the electrical system to deliver continuous and uninterrupted power.



Measures to improve reliability:

• Backup Power Systems (UPS, Generators):
• Provide temporary power during main power outages to keep critical control systems running.
• Dual Power Supply Systems:
• Two independent power sources with automatic switching in case one fails.
• Power Isolation and Tiered Supply:
• Critical and non-critical devices are supplied separately, with priority given to key equipment.
• Power Monitoring and Alarm Systems:
• Real-time monitoring to detect anomalies and trigger backups or alerts.
• Electrical Redundancy Design:
• Use of redundant power modules (e.g., in PLC systems) to prevent single-point failures.
• Regular Maintenance and Inspection:
• Periodic checks of cables, transformers, and power equipment to prevent failures.

Power Quality and Supply Reliability in Power Systems

Power systems refer to those that supply electrical energy to drive mechanical equipment, industrial processes, or production lines (such as motors, variable frequency drives, electric heaters, etc.). The quality and reliability of the power supply are critical to ensuring efficiency, safety, and equipment longevity.

1. Power Quality

Power systems are highly sensitive to power quality. Poor power supply conditions can lead to reduced efficiency, overheating, or even serious equipment damage.

Common power quality issues:

• Voltage deviation:
• Overvoltage can cause motor overheating and insulation degradation.
• Undervoltage makes starting difficult and reduces motor torque.
• Voltage fluctuations:
• Lead to mechanical instability, vibrations, and affect devices like frequency converters.
• Voltage sags and momentary interruptions:
• Can cause unexpected shutdowns or protection device triggers, disrupting continuous production.
• Harmonic interference:
• Caused by nonlinear devices such as inverters and converters.
• Can interfere with other equipment and cause false trips.
• Use harmonic filters (active or passive) to mitigate.
• Three-phase voltage imbalance:
• Causes motor vibration, efficiency loss, and potentially motor damage.
• Frequency variations:
• Less common, but may affect motor speed and system synchronization.
• 
  

2. Power Supply Reliability

Power supply reliability is essential for the safe and continuous operation of power systems—especially in continuous production lines or critical equipment, where an unexpected power outage can result in major losses.

Measures to improve reliability:

• Dual power supply systems:
• Two independent power sources with automatic switching to prevent power loss.
• Backup generator systems:
• Especially suitable for critical workshops, elevators, pumping stations, etc.
• UPS systems with bypass function:
• While mainly used for control systems, some motors or servo mechanisms can also benefit.
• Redundant electrical distribution design:
• Critical equipment with dual power sources, dual inlets, and dual feeders.
• Online power monitoring and alarm systems:
• Real-time monitoring of voltage, current, power, and load to detect anomalies early.
• Preventive maintenance and periodic inspections:
• Include checks on cables, switches, grounding systems, capacitor banks, etc.
  

Power Quality and Supply Reliability in Transmission and Substation Systems

Transmission and substation systems are the central components of the power grid, responsible for transporting electricity from generation sources to end-users. The power quality and reliability in these systems directly affect the stability, safety, and continuity of the entire electrical network.

1. Power Quality

Power quality in transmission and substations primarily refers to the stability of voltage, frequency, waveform integrity, and the absence of interference during energy transfer.

Key factors and corrective measures:

1. Voltage stability

• Issues: Voltage drops at the end of long lines or due to sudden load changes.
• Solutions: Automatic Voltage Regulators (AVR), reactive power compensation, capacitor/reactor banks.

2. Frequency stability

• Affected by generation-load imbalances.
• Solutions: Frequency-regulating power plants, energy storage systems, demand-side management.

3. Harmonic distortion

• Caused by nonlinear loads (e.g., heavy industry, inverters, rectifiers).
• Solutions: Active/passive filters, harmonic monitoring, distortion limit standards.

4. Transient overvoltages and surges

• Caused by lightning strikes, switching operations, or equipment faults.
• Solutions: Surge arresters, suppression devices, special disconnectors.

5. Three-phase voltage imbalance

• Caused by asymmetrical loads or line configurations.
• Solutions: Load balancing, phase adjustment, compensating devices.
• 
  

2. Power Supply Reliability

Reliability refers to the system’s ability to deliver uninterrupted power or to quickly restore service after a disturbance. In transmission and substation systems, this involves redundant design, protection schemes, smart monitoring, and rapid recovery.

 Key measures to enhance reliability:

1.Meshed or multi-source networks

• Increase redundancy: if one line fails, others maintain the supply.

2. Dual transformer and busbar configurations

• Use of double busbars or main transformers in critical substations.

3. Smart monitoring (SCADA, PMUs)

• Real-time tracking of voltage, current, power, and frequency for fast fault response.

4. Differential protection and fast fault isolation

• Accurately identifies and isolates faulted sections to prevent widespread outages.

5. Backup systems and emergency dispatch capability

• Integration of energy storage, mobile generators, and spare transformers.

6. Predictive maintenance and routine inspections

• Techniques include infrared thermography, partial discharge detection, and online insulation monitoring.
