| Abstract |
At the present time, reliability and stability of electric power have been very important when it comes to
electrical systems in any plants, especially in terms of distribution. Phoenix Pulp & Paper PCL (PPPC) in Khon
Kaen, Thailand, is currently generating electric power about 90% of its current needed by themselves and buys the
rest from Provincial Electricity Authority (PEA). Nonetheless, the protection system should be installed to protect
the electrical bus when electrical generating process trips or breakdown. Otherwise, it would cause the shutdown of
electrical system and lose all manufacturing. To protect electrical system, PPPC therefore has to use load shedding
system for cutting the connection of the machines from the system within few minutes. Power flow of electric power
from 115 kV PEA to 11 kV via 2 transformers of 115 kV/11 kV and PPPC’s 3 generators are studied in this research
by setting the real electric power (P), reactive electric power (Q), current (I) and voltage (V) in the protection relay of
load shedding system of 11 kV switchboards. In addition, motor control panel, simulated by SKM Power Tools
program, is investigated in this research work. The simulation results: P, Q, I and V will be divided into 4 cases: the
trips from TG-PUC, TG2, TG3 (in-house generation) and the one from PEA. In the case that there is a trip from PEA
electrical distribution, P, only generated from the first three generators in house, will be insufficient to cover the
plant’s electric need and require around 6,512 kW more. As a result, the machines would have to be stopped running.
However, if there is a trip from its in-house generation (TG-PUC, TG2 and TG3) instead, some P can be directly
received from PEA. Thus, the load shedding scheme is important to protect the blackout system from electrical
system’s trip in distribution. |
