SYSTEM OF SELF-SUFFICIENCY OF ELECTRICITY IN PEAK HOURS The generation system has a design capacity of 7.24 MW, to operate during peak hours and during times when there is no provision for the commercial network, composed of four generators operated with diesel and synchronization boards. MODES OF OPERATION Peak shaving operation mode (peak times): - The system turns on automatically according to a schedule based on the times tips the utility. Generators are synchronized by a 4160 V and the voltage transformer rises to 23 KV and connected to the commercial network in transferring the load smoothly generators such that there are no changes in energy parameters (voltage, frequency and current) during the transition between the commercial network and the autogenous group. Emergency mode: -In case there is a power outage in the commercial network, the generators start at eight seconds and synchronized taking charge 100% Upon return of utility power, the system synchronizes with the network generators transferring the load smoothly without any variation in energy parameters (voltage, frequency and current) Peak Shaving System Tablero eléctrico de sincronización 10 MVA Carga Site Tultitlan 23 KV Red comercial 23 KV Transformador 23 kv 4 kv TC 1 SINCRONIZACIÓN TC 2 TC 3 Tablero eléctrico de transferencia TC 4 10 000 lt 2000’KW 2000’KW MOTOGENERADOR 4 MOTOGENERADOR 3 MOTOGENERADOR 2 MOTOGENERADOR 1 10 000 lt 2000 KW 10 000 lt 10 000 lt 2000’KW Tanques de Diesel Grupo de generadores
