Common use of Synchronous Generation Clause in Contracts

Synchronous Generation. Units or groups of smaller units in one location with individual or total aggregate capacity greater than 1 MW must use synchronous generators, with speed-droop governors and high-speed excitation systems. Individual units should have a minimum operating capability of .90 lagging to .95 leading power factor at rated real power output. At times, SPPCo. may require direct or indirect voltage or power factor control of these units to maintain acceptable system operation. Exception: Units or groups of units connected directly to the distribution system (SPPCo.'s 25 kV or below electrical system) must be reviewed for safety, security, and transient response associated with islanding conditions. This review may dictate a requirement for induction rather than synchronous generation. SPPCo. will specify induction or synchronous generation in these cases subsequent to the interconnection/transient studies.
