This guide applies to voltage and reactive power control in 1000 kV and above ac systems. It establishes criteria and requirements for electric power utilities in the planning, design, infrastructure, operation, and scientific research of voltage or reactive power in 1000kV and above ac systems, which should guarantee the system stability and equipment safety. Keywords: 1000kV ac, IEEE 1860, reactive power balance, ultra-high voltage, voltage adjustment, voltage deviation, voltage and reactive power, voltage regulating.

This standard pertains to ferroresonant voltage regulators that operate at relatively constant frequencies and provide substantially constant output voltages in spite of relatively large changes of input voltage, and to controlled ferroresonant regulators that maintain substantially constant output voltages regardless of variations, within limits, of input voltage, temperature, frequency, and output load. Guides to application and test procedures are included. Provision is made for relating the characteristics of ferroresonant regulators to associated rectifiers and circuits. Definitions pertaining to ferroresonance and ferroresonant regulators that have not been found elsewhere are included with an appropriate discussion. This standard includes, but is not limited to, the following types of ferroresonant regulators: (1) series ferroresonant regulators; (2) series-parallel ferroresonant regulators (electrically connected); (3) ferroresonant transformer regulators (magnetically coupled); (4) controlled ferroresonant regulators.

Qualification methods for Class 1E vented lead acid batteries and racks to be used in nuclear power generating stations outside primary containment are described in this standard. Qualifications required by IEEE Std 308(TM) can be demonstrated by using the procedures in this standard in accordance with IEEE Std 323(TM). The application of batteries in nuclear power generating stations can be divided into two sections: duty cycles equal to or less than 8 h and duty cycles greater than 8 h. A process to demonstrate qualifications for both applications is provided in this standard.

A technical basis for implementation of electronic power subsystems is provided in this recommended practice. It is intended for electronic systems engineers and integrators, electronic power subsystem designers and integrators, as well as for power element manufacturers and suppliers. System-level issues in element or subsystem integration, adaptation, and accommodation are addressed, and system interface parameters, test methods, and test conditions are defined. Ac-dc, dc-ac, and dc-dc electronic power subsystems are discussed. The range of electronic power subsystems includes those with dc, single-phase, and three-phase inputs, having power levels from a fraction of a watt up to 20 kW. The voltage range is 600 V and below at a frequency or frequencies of dc 1 kHz. Internal operating frequencies within elements or subsystems may be much higher than 1 kHz. This recommended practice may be used outside the range where applicable. IEEE Std 1515-2000 is built on and supplemented in this document.
