The operation of a power station becomes more complex because of variable loads. The primary objective of any power plant is to fulfill the load requirements of consumers. In an ideal scenario, a constant and steady load would be preferred in terms of required equipment and operating routine. However, such a steady load is rare … Read more
A load duration curve abbreviated as LDC is very often used by Power Engineers in the field of electric power generation to demonstrate the relationship between generating capacity requirements and capacity utilization. A load duration curve is a graphical representation of the load elements of a load curve arranged in descending order of magnitudes. This … Read more
The economizer is a device employed in steam power plants to improve the efficiency of the steam cycle by preheating the feedwater entering the boiler. The economizer is essentially a heat exchanger that recovers the heat from the flue gases leaving the boiler and uses it to preheat the water before it enters the boiler. … Read more
In order to ensure the economical operation of steam power stations, below factors should be considered:
Feed water in a steam power plant refers to the water that is provided to the boiler for conversion into steam. Feed water is actually the condensate from the condenser that is used as feed water to the boiler. Feed water is subjected to a treatment process so as to eliminate impurities and minerals that … Read more
Electrical Power Station also sometimes referred to as Generating station or simply a power plant is a specialized facility that produces bulk electric power. The basic construction of plants comprises a prime mover coupled with an alternator, which works together to produce electric power. The prime mover can take various forms, it can be a … Read more
Electrical power equipment is rated in terms of VA or kVA. When an electrical load has voltage V across it and current I through it, the power that appears to flow to it is a product of V and I that is VI. However, if the load comprises of both resistance and reactance, this product … Read more
The term active power is related to AC power systems and it defined as the average power delivered from a source to a load. It is also known as real power or average power. The active power is the amount of electric power in an AC electric circuit that is actually consumed or utilized. Active … Read more
