Solutions for Problems from“Two Regulations” Assessment of Jinjitan Hydropower Plant

HE Bo;Jinjitan Hydropower Plant of Datang Guangyuan hydropower Generation Co., Ltd.;  
"Two Regulations"assessment is one of the important assessment methods that power grid corporation evaluates the power plant in present stage, which is composed of primary frequency regulation and power generation plan assessments. Jinjitan hydropower plant spent much money on its "Two Regulations"assessment due to its poor qualified rate of primary frequency regulation resulting from wrong direction or insufficient accumulated power quantity of regulation; as well as the poor regulating performance of unit automatic system, the practical load curve deviating from the planed load curve. In order to reduce the unnecessary costs on assessment, the related equipment parameters of unit were adjusted and tested, which improved the qualified rate of primary frequency regulation and the regulating performance of unit automatic system, ensured the practical load curves are in limited range and obtained very good economic results. Therefore, the mentioned method for reducing the unnecessary costs on"Two Regulations"assessment is feasible.
