This paper presents the application of WAMPAC System in Paraguay’s ANDE Power System. The different stages starting from power system studies over testing to commissioning in the field are described. The project had the goal to secure inter-connected operation of ITAIPU hydro power plant and YACYRETA hydro power plant through ANDE’s power system.
The already implemented ECCANDE (Esquema de Control ante Contingencias de Ande) WAMPAC
system ensures the stability by using PMU measurements from critical circuits and substations as well
as the status of various circuit breakers. Different criteria like voltage angle differences and active power
flows are used to initiate corrective actions like system separation and load-shedding. A pair of
redundant Phasor Data Concentrators (PDCs) from SIEMENS (SIGUARD PDP) is in service to observe
the measurements and to decide which actions are required.
Within this paper the authors will share the learnings and experiences during the whole process of
implementing such a complex WAMPAC system.
