The Role of Industrial and Domestic Biomass Boilers
What is Biomass Energy? Biomass energy, a form of renewable energy derived from organic materials, has gained significant attention as a sustainable energy source. This type of energy is produced from biological substances such as wood, agricultural residues, and even certain types of waste. These materials, collectively known as biomass, can be directly burned or…

The Essential Role of Water Turbines in Harnessing Hydroelectric Power
Understanding Hydroelectric Power Hydroelectric power is one of the most efficient and widely used forms of renewable energy. By harnessing the kinetic energy of flowing water, hydroelectric power stations generate electricity with minimal environmental impact compared to fossil fuels. In essence, hydroelectric power utilises the natural water cycle, converting potential energy stored in water at…

Maintenance Tips for Power Transformers
Maintenance is a routine and recurring activity of keeping a particular equipment or facility at its normal operating condition so that it can deliver its expected performance or service without causing any loss of time on account of accidental damage or breakdown. In other words, maintenance can be described as measures adopted to ensure that…

The Problems Associated with Embedded Power Generation
The rate of the development of energy sources that are alternatives to hydrocarbons is happening at a greater pace than any other time before; this is mainly because of the environmental reasons i.e. the limitation of carbon dioxide emissions and for the longer-term sustainability of energy supplies. The role played by such alternative energy sources…

The Effects of Low Power Factor on Electrical Equipment
The cosine of the angle between voltage and current in an AC circuit is referred to as the power factor. In a typical AC circuit, there is a phase difference Φ between the voltage and current. The term cos Φ is termed to as the power factor of the circuit; if the current is inductive,…

Synchronous Compensators, What is their Purpose in Power Systems?
When designing a transmission or distribution system, the engineer must take into account not only the power requirement of the loads, but also the fact that they consume reactive power and to the same degree key, that networks include inductive and capacitive components which themselves absorb or generate reactive power. Power is generated and consumed…

What is the Function of Unified Power Flow Controller?
In a number of cases, it may be possible to increase the grid’s capacity through enhanced control of the active and reactive power flow in the transmission network independently of busbar voltage. The Unified Power Flow Controller (UPFC) provides the reactive shunt compensation, active and reactive series compensation and phase shifting. It is thus capable…

The Connection of Green Energy Generation Plants to Power Systems: Key Factors to Consider
To prevent negative effects on the operation of the power system and equipment, a number of factors must be considered when connecting green energy generation plants to these systems. The following should be factored in: With the increased development of green energy generation plants, special aspects need to be considered such as the use of…

Causes of Power System Disturbances & Corrective Measures
Even though most protective system designs are built around individual components, system-wide disturbances in power systems are rather a frequent occurrence and a challenging issue for electric utility companies. When major disturbances occur in power systems, it is imperative to implement coordinated protection and control actions to stop the system degradation, restore the normal state…
