Suppose in a hyro-power plant, there are two generators, G1 and G2 of 11KV output voltage. The Transmission Voltage is 132KV. There are 2 11 Kv/132 Kv transformers. So, should we connect each generator separately to the Transmission line and synchronize individually OR should we first connect both generators in parallel (at 11 KV bus bar) and synchronize them before connecting to the grid. Whats better?
