Rate-of-return regulation (also cost-based regulation) is a system for setting the prices charged by government-regulated monopolies, such as public utilities.It attempts to set prices at efficient (non-monopolistic, competitive) levels [1] equal to the efficient costs of production, plus a government-permitted rate of return on capital.
An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. 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 ...
voltage regulators, which are essentially transformers with tap changers to adjust the voltage along the feeder, so as to compensate for the voltage drop over distance; and; capacitors, which reduce the voltage drop along the feeder by reducing current flow to loads consuming reactive power.
shunt capacitors are used in power systems since the 1910s and are popular due to low cost and relative ease of deployment. The amount of reactive power supplied by a shunt capacitor is proportional to the square of the line voltage, so the capacitor contributes less under low-voltage conditions (frequently caused by the lack of reactive power).
If the mechanical regulator design is sensitive to small voltage fluctuations, the motion of the solenoid core can be used to move a selector switch across a range of resistances or transformer windings to gradually step the output voltage up or down, or to rotate the position of a moving-coil AC regulator. Early automobile generators and ...
This is the total amount of money a regulator allows a utility to collect from customers. O is the utility's operating expenses, which are passed through to customers at cost with no mark-up. Examples include labor (for everything from field repair and maintenance crews to customer service and accounting personnel); bad debt expense; interest ...
Digital shelf labels will lessen the burden of updating prices on 120,000 items at Walmart stores. Walmart is replacing its price labels with digital screens—but the company swears it won’t ...
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
