Sažetak
According to the project POWER III, the rehabilitation of the power system of Bosnia and Herzegovina (BiH) and its reconnection with Croatian power system will be finish by the end of 2005. Use of available resources under constraints imposed by actual and prospective states of the power systems of BiH and Croatia (particularly Adriatic lines) leads to operational problems: violation of (n-1) criteria, high voltages, voltage instability, thermal power plants (TPPs) operating below minimum, etc. Having outstanding capabilities, pumped storage HPP Čapljina (2x240 MVA) could contribute to mitigating some of those problems while fully exploiting its advantages on the open electricity market. Two system services should be provided for HPP Čapljina: asynchronous start (with and/or without phase reactors at the generator star point) and transmission capacity for pumping. To find out if these services are available before rehabilitation of the power system a study was done and results are outlined in this paper. Regarding voltage / reactive power dynamics, asynchronous start of units at HPP Čapljina with phase reactors is possible, but reactive capability of nearby generators is fully used. With the other machine at HPP Čapljina operating as generator voltage/reactive power conditions in this part of the system are significantly improved. Two variants of supplying power for pumping were considered, from TPPs in BiH and from UCTE. In the latter case the constraint is violation of the (n-1) criterion for Adriatic lines in the Croatian power system.
