The two regulation schemes are a high-pressure feedwater bypass scheme and a low-pressure condensate bypass scheme. The present invention formulates a primary frequency regulation control logic, so as to efficiently and accurately participate in the primary frequency regulation, thereby keeping the power grid frequency rapidly stable. The present invention also formulates a working fluid outlet temperature control logic for the solar aided coal-fired thermal system, which adjusts a heat exchange working fluid flow of the solar collectors to ensure that the temperature in each section is stable during the primary frequency regulation. The present invention uses operation matching of the turbine system and the solar collectors to improve effectiveness of the primary frequency regulation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solar aided coal-fired power generation system participating in primary frequency regulation and control method thereof","description":"A solar aided coal-fired power generation system participating in primary frequency regulation and a control method thereof propose a system configuration with two regulation schemes by coupling mediu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11236633","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.
