Intelligent power management and control-a maintenance view

The requirements and application of intelligence power monitoring and control (IPMC) for power systems in central office, CDO and remote/radio sites are described from a field maintenance point of view. The IPMC system is designed to provide the same degree of power management and control of power systems that is currently provided for switching and transmission facilities. The system is an onsite, processor-based system that automatically performs surveillance data collection, testing, on/off line analysis and control of all components of central office power plants. This control includes emergency generators, UPS (uninterruptible power supply) systems, and AC switchgear. Because of its open architecture, the intelligent power system at one trial site also includes security (door card reader and perimeter) monitoring as well as fire escalation calls. The IPMC will extend power expertise for maintenance and reinforce the power reporting capability by directing help calls to key power personnel.<>
