1. IntroductionThe digital control system of Pylos SS has been designed by PSP (Power Systems Protection) to cover all the operational requirements of the particular Power Substation. With this SCADA system the operator of the Power Substation has the ability to monitor the operation at any time, to refer to historical data and perform operations on the CBs and the rest equipment of the installation.
2. VisualizationThe SCADA system offers the operator a variety of panels in order to supervise the whole installation in detail. Specifically there are the following panels:
General view of the Power Substation / 150kV Detail
20kV Detail / Power Transformer Detail
110VDC Distribution Detail / 400VAC Distribution Detail
Relays Communication Detail
3. ControlFinally, the SCADA system offer the ability of controlling the equipment. The installation consists of one 150kV CB, one 150/20kV Power Transformer with OLTC and 6 20kV CBs. Via the SCADA system the operator can control the OLTC’s позиция, reset the Lockout Relays of the installation and open or close the CBs always respecting the safety interlocks which are automatically checked by the SCADA system and allow or forbid the each control that is going to be performed. Если a control is forbidden, then there is always a message explaining which interlock is active in order to inform the operator for the actions that he must do before the specific control.
