Patent number: 8565929Abstract: Methodology is provided for enhancing plant level support for grid reconstruction following a blackout. A plant based grid reconstruction manager develops solutions for reconstruction sequence steps to be carried out automatically or to be communicated to site personnel for manual implementation. The sequence steps are based on high-fidelity modeling of the capabilities all of the power production units present in a power plant and take into consideration grid specified load expectations, ambient conditions including ambient temperature and gas turbine operating levels. The methodology also provides for consideration of possible subsequent steps in the sequence to maximize the ability to pick-up additional load in such subsequent steps.Type: GrantFiled: November 17, 2010Date of Patent: October 22, 2013Assignee: General Electric CompanyInventors: Christopher Eugene Long, Laura Lea Boes
