Most of this data is generally compiled on daily basis at the Power Stationlevel and at HQ level for generation of Management Information Reports.Generally following reports, logs, reading sheets are required to be prepared atdifferent levels of management structure:Typical Plant Data Sheets:-(ix) Hourly panel meter readings Control room(x) Station event log book Control room(xi) Station trouble/fault log book Control room(xii) Energy meter readings Control room(xiii) Daily generation reportControl room(xiv) Hydraulic data sheet Control room(xv) Daily rainfall, lake level Control room(xvi) Monthly generation & aux. consumption report Plant Manager(xvii) Monthly water consumption & runoff reportPlant Manager(xviii) Occurrence and relay tripping reportPlant Manager(xix) Special event report (eg. Landslide, fire etc.) Plant Manager(xx) Accident report (involving human being, animals) Plant Manager(xxi) Quarterly safety & fire drill, training imparted at plant Plant Manager2.5 GUIDELINES FOR SAFETY MANUAL(i) Every power plant shall have safety manual, copies of which shall be given toevery employee. The safety manual shall contain:• Safety policy of the organization• Safety during work• Outage procedure with safety tags.(ii) The management shall conduct safety training for operation and maintenance staffon regular basis.AHEC/MNRE/SHP Standards/ E&M Works – Guidelines for Operation and Maintenance of Small Hydropower Station 11
