It matches boiler of conespondmg capacity and steam turbine generator to form thermal generation unit. It is of basic load in electricity grid, and can also regulate the peak.The control system of tliis unit is low pressuie electric regulation.控制系统是低压电液控制This iiistiiiction manual mauily describes tlie general design of the unit and tlie stmctuie of tlie tuibme proper. Please refer to related teclinical documents provided with the machme for detailed descriptions on related auxiliaries, governing, protection and safety systems, installation and maintenance, stait-up and operation, and vaiious systems If the instmction conflicts with teclinical documents provided, the documents shall prevailIn this iiistiiiction the pressures for the thermal system are presented in absolute pressure. The instmction uses legal measurmg units system which can be converted .into engineeiiiig measuring units by means of the following:Force: 1 kgf = 9.8067 N Pressure: 1 kgf / cm2=0.098067 MPa Heat: 1 kcal = 4.1868 KJNote: definitions of Hleftn and right” sides: Being viewed in the duection from tlie steam turbine towards the generator; the left hand side is defined as the nleftM side whereas the right liand side is defined as the HrightM side.
