I'm interested in getting the names of manufacturers of Supervisory Control and Data Acquisition (SCADA) equipment/systems for utility type electrical power distribution systems.
For small to medium-size systems (the size of most medium/large municipal utilities), I'd recommend either:
Advance Control Systems (ACS) Atlanta or
Open Systems International (OSI) Minneapolis
Both have excellent reputations.
For SCADA consulting to determine requirements and help develop procurement specification, project management, test witnessing, technical consulting, etc., there's no better than KEMA Consulting (Chalfont, PA; (215) 997-4500). Two good consultants there I've used are:
Bob Uluski and John McDonald. John has recently been elected President of the IEEE Power Engineering Society so may not be taking on much new work.
A word of caution on ACS - we are moving away from ACS for a couple of reasons:
1. They are very proprietary - therefore there is no competetion - you have to use their equipment.
2. The version we have is a unix based system and requires HP computer equipment - again no competition.
3. Because of 1 & 2, it's hard to interface with other outside equipment.
We have recently upgraded our SCADA system to a Windows based dual master system. We chose Survalent Technologies. The new system has been online for 1.5 years. The customer support is second to none. Highly recommended!!
If you have a technical design question most of the time you are talking to the engineer that designed it. Everyone at Survalent is eager to solve a problem. They also have great user group meetings.
