Excitation Systems Sample Clauses

Excitation Systems. The generators shall be provided with fast-acting high initial response excitation systems of the rotating brushless type or of the potential-source-rectifier type. Brushless exciters are preferred. A crowbar system shall be provided to allow for negative current in case of pole slip. Each excitation system shall have enough capacity to allow the corresponding generator to operate at its maximum continuous operating voltage and at the rated power factor under all ambient conditions. If static design, the excitation system shall have the ability to change out exciter brushes on-line. Potential-source-rectifier exciters, if supplied, shall be provided with a field circuit breaker and discharge resistor having an inverse voltage characteristic. The excitation system shall be provided with automatic and manual voltage regulators. The automatic voltage regulator (AVR) shall maintain the terminal voltage of the generator at the value set by the operator, with negligible drift, throughout the whole operating range without instability and will comply with WECC requirements. The manual regulator will be used for test purposes and as a back up in case of failure of the AVR. An automatic follower shall be provided between the AVR and manual regulator so that a bumpless transfer can be made between them. The excitation system shall have the following features and functions: Minimum excitation limiter Maximum excitation limiter V/Hz limiter Reactive drop (line drop) compensation Cross current compensation Redundant power bridge and controls AVR failure detection with automatic changeover to the backup channel without the need to trip the unit Internal electronics diagnosis and failure detection alarm and trip functions as needed Power system stabilizer - PSS test report shall be prepared and submitted for California ISO approval All semiconductor components used in the excitation systems shall be conservatively rated and protected from transient surges to ensure reliable operation and service. Protections included in the excitation systems shall include over-voltage, over-current, fuse failures of the potential transformers, and power supply failure to the AVR, as well as thyristor and pulse failure functions in case of potential-source-rectifier exciters, if supplied. The excitation system shall operate in conjunction with the turbine starting equipment in case that solid state starting equipment is supplied.

  • Irrigation Systems The Project Area either has no irrigation system or a low-volume drip irrigation system. If a watering system is used, it is a drip irrigation system equipped with a filter, pressure regulator and emitters rated at twenty (20) gallons per hour (gph) or less. The system is maintained free of leaks and malfunctions. No spray irrigation is applied to the Project Area, including spray from irrigation systems adjacent to the Project Area.
