Energy conversion efficiency ( η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. [ 1][ 2][ 3]
Load-following power plant. A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. [1] Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and ...
Power plant engineering. Power plant engineering, abbreviated as TPTL, is a branch of the field of energy engineering, and is defined as the engineering and technology required for the production of an electric power station. [1] Technique is focused on power generation for industry and community, not just for household electricity production ...
The power-flow study is an analysis of the system’s capability to adequately supply the connected load. The total system losses, as well as individual line losses, also are tabulated. Transformer tap positions are selected to ensure the correct voltage at critical locations such as motor control centers. Performing a load-flow study on an ...
Power plant efficiency. The efficiency of a plant is the percentage of the total energy content of a power plant 's fuel that is converted into electricity. The remaining energy is usually lost to the environment as heat unless it is used for district heating . Rating efficiency is complicated by the fact that there are two different ways to ...
Load factor (electrical) In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [ 1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or ...
In an electric power system, automatic generation control ( AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary.
Utilization factor. The utilization factor or use factor is the ratio of the time that a piece of equipment is in use to the total time that it could be in use. It is often averaged over time in the definition such that the ratio becomes the amount of energy used divided by the maximum possible to be used. These definitions are equivalent.
