Provision of Transmission Substation Management Console [TendersInfo (India)]


(TendersInfo (India) Via Acquire Media NewsEdge) Tenders are invited for Transmission Substation Management Console. Vendor Questions Conference : April 30, 2014 9:00 10:30 a.m. PDT. Background. Seattle City Light (SCL), a department of the City of Seattle, is a municipally owned and operated electric utility which provides generation, transmission, and distribution services. City Light serves approximately 400,000 residential, commercial, and industrial customers in Seattle and adjacent jurisdictions, making it the 10th largest public electric utility in the United States, based on energy sales. As part of its network, City Light maintains 16 transmission substations in the greater Seattle area. At each substation, City Light currently uses conventional remote terminal unit (RTU) technology to monitor digital and analog points and to control equipment from the System Operation Center (SOC). Schweitzer Engineer Laboratories (SEL) provides the standard relays; standard revenue meters are Schneider Ion 8650 s. There are no communications protocols used within substations. The RTUs link to the SOC via Telegyr 8979 protocol. SCL intends to install a new, server-based communications and monitoring system (a substation management console or SMC) in each substation. The SMC is expected to consist of a console ( hardware ), operating system and communication protocols, and user interface ( software ) although the exact functions and relationships of these (and potentially other) components are subject to discovery via this RFI. The SMC will be acquired in order to facilitate the following: Increased data availability from new Intelligent Electronic Devices (IEDs) such as digital meters and relays. Improved alarm management by eliminating combined alarms while also creating smart alarms, programmed to determine and display the root cause of a problem, to reduce alarm flooding. Increased reliability of the alarm system by replacing outmoded signaling devices with video displays. Preparation for the implementation of Smart Grid technology such as distribution automation, advanced metering, and voltage control management systems. Implementation of secure remote access to information from outside the station for both engineering and maintenance purposes. Implementation of on-line condition monitoring. SCL is currently in the process of updating its Energy Management System (EMS). SCL expects that the new SCADA protocol between the EMS and the stations will be DNP3.0, either IP-based or serial. A future option of using IEC61850 protocol for EMS communications is also desirable. Requirements. City Light expects to acquire dual (primary and back-up) substation management consoles for each substation. Each will be based on an appliance or other dedicated computing hardware platform at the substation which will gather information from a network of sensing devices (IEDs) within the substation and send that data to other computer systems outside the substation.
