Precise power plant reduces battery size and harmonic feedback at telecommunication sites

"Written-Pole" technology has been patented and developed for electric motors and generators that advances the state-of-the-art for electrical energy storage systems. Very effective and efficient use is made of the inherent flywheel energy stored in the rotor of a unique motor-generator set. The machine is not only the ultimate on-line power conditioner, but is also an electro-mechanical battery that delivers useful precise frequency AC power and DC power for extended time during utility power sags, surges and blinkouts. Then when power interruptions extend into blackouts (after 15 or more seconds), the precise power plant engages, and using flywheel energy, starts an integral gas or diesel engine, or it may alternatively tie into the station's existing engine generator for a no-break transfer. The written-pole motor is synchronous and reflects a unity power factor, sine wave load to the utility, while the generator mitigates all the harmonic loads imposed by the switching power supplies and other devices in the telecommunication site. This paper discusses the written-pole technology, shows an operational design with specification and test results, applications in telecommunication sites, as well as other commercial and industrial areas.<>
