'While the sector has an estimated available capacity of 7,000 MW, of which, on a daily basis, 2,000 MW remains constrained by lack of gas (specifically, an average of 1,500 MW, given that 25 out of 28 of our generation plants are gas-powered thermal plants) caused by an inadequate and incomplete gas pipeline structure and the absence of a strong commercial framework that will spur gas exploration and sales; and the balance of 500 MW is limited by transmission line frequency challenges, transmission line limitations and hydro constraints,'it stated.
They are generally dependent on the line frequency and structural characteristics of the machine [5].
Glow discharge plasma was generated around the substrates, with a power of about 40 W at standard line frequency of 50 Hz.
* The use of line frequency AC input transformers to provide galvanic isolation adds significant size and weight to the product, especially as power levels increase.
The high bulk capacitance is not compulsory, since the voltage ripple across this capacitor at the double line frequency can be attained by closed-loop operation.
[25] presented the thought of stage wise matching pursuit and then proposed the line frequency modulation wavelet path tracking method.
[omega] is the angular frequency 2[pi][f.sub.L], [f.sub.L] is the line frequency, e.g.
--50 Hz power line frequency generated inside Matlab;
In order to ensure maximum magnetic flux transition, the power transfer coils are terminated with parallel capacitors for LC resonance at a specified power transfer line frequency. The line frequency of power transfer was designed to be variable between 40 kHz and 600 kHz for the specific telemetry application.
Although there are many practical solutions to reduce the PLI, for example, the cable twisting and shielding, the use of differential recording involving an instrumentation amplifier with high common mode rejection ratio (CMRR) at power line frequency, and the proper skin preparation to reduce the electrode imbalance, the PLI still affects the biopotential measurements.
