Municipal TS’s - May 2003 Virelec supplies SCADA system Virelec was contracted by ALSTOM (now AREVA) to supply the SCADA system for the Dundas and Winona transformer stations, which Hydro One built for Hamilton Hydro in Ontario. The TS’s were fast-tracked to meet the growing load demand in the city, prompting Hydro One to choose a “drop-in” approach, with the GIS MV switchgear and the associated protection, control and SCADA system housed in a pre-fabricated “e-house” building. The Hydro One Station Process Control Network (SPCN) is a dual Ethernet network configured with fibre-optic hubs interconnecting the various IED’s in the station. The main RTU is the GE D200, with four additional D25 RTU’s provided for direct analogue inputs, relay communications, digital inputs and outputs. The D200 is configured to communicate with a local control system comprising a DC-powered computer running the GE Powerlink Advantage control program. The system is also configured to communicate with the SCADA Master using the DNP3.0 protocol either serially or over TCP/IP.	Virelec supplied a fully-configured system with the D200, computer, HMI, satellite clock and modems housed in a separate panel, while the D25 RTU’s are housed in the MV switchgear along with the protection IED’s. The Factory Acceptance Test (FAT) was carried out in the e-house at AREVA’s premises in Montreal, prior to the dropping-in of the building at the substation site, considerably reducing the burden of site commissioning. The Dundas and Winona TS's were commissioned within twelve months of the order date, and deemed so successful that Hydro One implemented the same design and procurement model for two more substations in 2005 - Midhurst TS in Barrie and Cardiff TS in Mississauga.
