The control device includes: a voltage and current measurer to obtain, from a single-phase system voltage, an angular velocity and a phase of the system voltage by an estimation operation that uses the phase of the system voltage as a parameter; a power obtainer to obtain active power and reactive power; a governor model to calculate a phase difference; an AVR model to calculate an absolute value of an induced voltage of a virtual synchronous generator; a generator model to calculate current command values corresponding to an armature current of the virtual synchronous generator; and a current controller to generate and output a PWM signal to the power converter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device connected to single-phase system","description":"A power conversion device includes: a power converter to perform output to an output line connected to a single-phase power system; and a control device to control the power converter so it operates a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9768712","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
