5.5 Power Network Simulator

The lack of sufficient computer power led to the failure of a number of projects for
the development of training simulators for complex facilities. The design team for
the power network simulator project led initially by Leading Designer 4 did not try
to implement the detailed online simulation model, as this would not have been
feasible with the computers then available in Poland which lacked sufficient pro-
cessing power. Instead, they used their knowledge as experienced power network
control engineers to derive a simulation based on characteristic power network
responses. The project was very successful. The simulator operated for about 12
years, and during this time the overwhelming majority of power network control
engineers in Poland were successfully trained on it (Fig. 8.10 ).

5.6 Microprocessor-Based SAPI Realisation

The demanding requirements of the Odra 1325 computer, particularly the need for
air-conditioned rooms and the associated high costs, especially for the lower levels
of the power distribution system, led to the development of a simplified version of
SAPI ODM, which was realised using microprocessor-based technology (Fig. 8.11 ).
