Ladle Arc Furnace Upgrade Project – Sheffield
£1.1m Electrical and Control system – Ladle Arc Furnace Upgrade Project.
Riverside ECS supplied and installed two MCCs and multiple remote I/O and sensor measurement control panels as part of a major electrical upgrade of the arc furnace completed by the Riverside Group.
The contract included a brand new control room building, floor and stair case with the new desk and computer monitors system (shown).
The complete system was successfully installed and commissioned within a three week production shut down window working extended shifts to meet the strict deadline.
The client commended the efforts of the design, build and installation teams, and was very pleased with the overall build quality and functionality of all the panels.
The project included an 8.4m long wardrobe style MCC arranged in a two row, back-to-back configuration. The mix of VSD and DOL motors starters controlled water, oil and hydraulic pumps, heater blowers, and air coolers totalling nearly 200kW. There was additional functionality for steel handling features all controlled by a Rockwell PLC system.
In addition, the client wanted a new water treatment plant MCC, which was a 4m long wardrobe style configuration with VSD and DOL water pumping capability totalling approximately 150kW.
Several large remote I/O panels distributed the control inputs/outputs signals over the whole site and these were routed back to the new control room and MCCs.
The panels were constructed from a mix of coated mild steel and stainless steel, depending on the location of the equipment and the IP rating was also determined by the environment into each panel was housed.
The successful project management was due to adherence to ISO9001, which also ensured this system was delivered on time, to cost and to the excellent quality that this client demanded.
WTW SCADA Upgrade – Surrey
The Automation upgrade of a major water treatment works for Affinity Water was completed by Riverside Automation successfully and within schedule.
Riverside were Main Contractors and had CDM responsibility for the project. Total value of contract to Riverside was £295,000.
The Automation scheme involved the upgrading and integration of existing Omron PLCs and Rockwell PLCs. A new site wide fibre optic network connecting key locations used 11 Industrial Ethernet switches configured to provide redundancy in the event of a component failure.
The SCADA system was an iFIX redundant system with failover from main to standby server computer. Five new client computers were included and an off site Wide Area Network link allows remote interrogation of the SCADA by Affinity Water engineers.
New control modes were added including the following process areas:
|Ultra Filtration||GAC Filters||RGF Filters|
|Borehole Pumps||Delivery Pumps||Flood Protection|
|Customer Protection||Overall Works Control|
Grid Control and SCADA solutions for renewable energy systems
Wind Farm Grid Control
Riverside has developed both Active Power Control and Reactive Power Control functions using a Grid Control system that acts as an interface between the network operator’s Remote Telemetry Unit (RTU) and the wind turbine control system.
Active Power Control accepts curtailment demands from the network operator, and also acts to correct variations in measured frequency by changing the amount of power demanded from the wind farm. Reactive Power Control can maintain either a Voltage Setpoint or a Power Factor Setpoint, as selected by the network operator.
Our HMI and Web-based solutions provide for the Display and Logging of information from a wide variety of substation HV supply equipment and Protection and Electrical Control including Sequence of Event reporting.
We can interface to external equipment such as Socomec Diris, GE Power Quality meters and Schneider ION meters with protocols such as DNP3, Modbus, Mitsubishi CC:link, IEC 60870-5, IEC 61850 and IEC101. In addition we are skilled in using OPC Server and Client technologies for Operators, Generators, and Distributors. We are experienced with various OPC implementations: OPC XML DA, OPC DA, OPC UA and can customise interfaces to provide tunnels between equipment.
We specialise in the integration of dissimilar and legacy platforms with new equipment. Particularly when a range of different manufacturer’s equipment might be in use at a Wind Farm and there is a need to maximise use of existing assets.
Other capabilities include the provision of ongoing support packages and assisting with grid code compliance testing and report preparation.
