The Static Synchronous Series Compensator (SSSC) is a series device of the Flexible AC Transmission Systems (FACTS) family using power electronics to control power flow and improve power oscillation damping on power grids. The SSSC injects a voltage Vs in series with the transmission line where it is connected. As the SSSC does not use any active power source, the injected voltage must stay in quadrature with line current. By varying the magnitude Vq of the injected voltage in quadrature with current, the SSSC performs the function of a variable reactance compensator, either capacitive or...

Nitrogen entering a farm through animal feeds ends up as ammonia in manure. Ammonia volatilization is a major process of N loss that affects the environment. The best way of capturing volatilized ammonia-N could be using zeolite as a good ion exchange medium before it gets either volatilized or nitrified. Thus captured ammonia-N could be used as a source of inorganic nitrogen in ponds to promote algal production without adding additional organic carbon and BOD. The nitrogen transferring mechanism developed not only avoided nitrogen loss but also could generate biogas, an additional income to...
