Points out that flexible Ac transmission system (FACTS), all-controllable power system and wide area phasor measurementsystem (WAMS) which base on synchronous phasor technique are new techniques from existing grid toward the future type grid. Discussesvulnerability of power system and communication system, and their valuation method, meanwhile aiming at the system vulnerability to estab-lish the strategic power infrastructure defense (SPID) system's basic concept and its necessity. Emphasizes that the WAMS is importantinfrastructure of strategy defense for the future type electric power system, and analyzes the factors, which influence of WAMS serviceabilitysuch as delay and response time etc. Suggests to develop and perfect the wide area grid intelligent adaptive multi-agent system (MAS) anddevelop the new generation information communication system based on fiber network.
