Power receiving and distribution to Load block substations in Large steel plants :

In large steel plants power is generally received at 220kV Switchyard or GIS Substation. It is stepped down to 33kV by step down transformers of approx. capacity of 100MVA. The 33kV Switchgear is normally air insulated or gas insulated type and has many outgoing feeders to load block substations at different load centers of the steel plant. The 33kV cables in the outgoing feeders are laid on cable trays in underground cable tunnels. The load block substations (LBSS) steps down 33kV to utilisation voltage of 6.6kV or 415V through transformers rated 20MVA or so. LT transformers are not rated above 2.5MVA. The entire power receiving and distribution system is controlled by a computerised data feedback and remote control system and it is essential to improve the power factor at the 220kV incomer.

Satcon has rich experience in designing of the Main receiving substation and downstream LBSS for large steel plants. Satcon has provided such designs for SAIL Bokaro and IISCO Burnpur. .

High voltage Switchyard Design and Engineering:

High voltage Switchyards are required for the following purposes :

1. To receive power at high voltage for various industries and then step down to lower voltages for distribution within the plant.
2. To receive power at high voltage by one or two incoming line feeders and then distribute to several locations or downstream substations at the same voltage. This type of of substation is called switching stations.
3. To receive power supply at lower voltages and then step up to high voltage for supplying power to grid substation. This type of substation is required for power generating plants.

The equipment and connections, bus bars are designed with respect to rated current flow through the feeders and bus bar. The short circuit current and duration also plays an important role in deciding the equipment and connection sizes.

The clearances (phase to phase, phase to earth, sectional clearances, ground clearances are decided as per CEA guideline or national or international standards.

Satcon is practicing such high voltage switchyard design for last two decades. We have very senior engineers who has high expertise to design any type of substation - AIS, Indoor GIS, Outdoor GIS for voltages upto 765kV..

𝐒𝐭𝐞𝐞𝐥 𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐃𝐞𝐬𝐢𝐠𝐧 𝐟𝐨𝐫 𝐄𝐇𝐕 𝐒𝐮𝐛𝐬𝐭𝐚𝐭𝐢𝐨𝐧𝐬:

In EHV outdoor Switchyards, to create sufficient ground clearance and phase to earth clearance, the live conductor heights from ground needs to be increased with the help of steel structures. Gantry Towers and beams are lattice type structures and equipment support structures are either lattice type or pipe type structures. These structures are designed as per Indian standard (IS) 800 or 802 by using staad pro software.

Satcon has very rich expertise of more than two decades in Steel structures designs for EHV substations for utilities and renewable energy projects. Such designs are delivered for overseas projects as well. For overseas projects, the designs are done as per relevant Eurocode or ASCE standard.

𝐂𝐨𝐧𝐭𝐫𝐨𝐥 & 𝐑𝐞𝐥𝐚𝐲 𝐏𝐚𝐧𝐞𝐥 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 :

In a Substation, Control & Relay panels are considered as the heart of the system. The Control and Relay panels can be separate panels or can be combined. The control panels, if sepatrated from the Relay panels, provide the control switches, alarm, annunciation, indication, interlocking and metering of the bay equipment either local manually or remote manually. Nowadays, a Bay control unit (BCU) is mounted on the control panel to monitor the entire operation of the bay and management from the control panel itself or from SCADA room HMI.

The Relay panels house the numerical protection relays of the bay along with auxiliary relays, contact multiplications, lock out relays, trip circuit supervision, lock out relay supervision, DC closing and tripping supply supervision etc. The Relay panel also interfaces with the Control panel for required interlocks and permissives.

Satcon is practicing such Control and Relay panel engineering for last two decades and has gathered very rich experience in preparing the Technical specifications, procurement assistance, vendor drawing review, preparation of scheme drawings of the CRP. Satcon can provide these services for substations of 765kV voltage or below.

Prebid Engineering services :

It is a type of engineering which is involved during preparation of a tender proposal for an industrial or utility project. In the public tenders, normally a price schedule blank format is provided by the Purchaser which needs to be filled up by the bidder to arrive at the lumpsum price. There are some items which are generally indicated in ‘lot’. One of the main purpose of the prebid engineering is to estimate the quantity of these LOT items and also to identify and quantify any missing items in the price schedule. This exercise gives the bidder a better control over the price he has quoted for the project.

The Prebid engineering comprises of preparing conceptual drawings (electrical, civil, structural, fire protection, HVAC and Substation automation system) - SLD, Layout plan and elevation, civil drawings and calculations, steel structural design and drawings, detail BOQ of all works and materials, list of assumptions while preparing the prebid BOQ and preparing a list of deviations from the tender requirement.

Battery Energy Storage System : Power generation through renewable energy sources like Solar and Wind is widely used nowadays due to climate related restrictions on fossil fuel based power generation. Renewable energy means of Power generation are reliant on weather conditions and hence availability of power from these type power sources need a storage system which storages the generated power and delivers it when weather conditions are not favourable. For example, solar power generation during night time is unavailable. Battery energy storage systems which use Lithium Ion or other type of Battery cells are one of the fastest growing technologies in the sustainable energy industry. Energy storage systems have become widely accepted as efficient ways of reducing reliance on fossil fuels and oftentimes, unreliable, utility providers. A battery energy storage system is the ideal way to capitalize on renewable energy sources, like solar energy. The adoption of energy storage systems is on the rise in a variety of industries. Satcon is being involved with several clients worldwide to participate in design and engineering of BESS for renewable energy projects. The scope includes selection of battery capacity, type, layout, control and protection schemes, connection diagrams, preparation of technical specifications. Satcon has the expertise and relevant standards to contribute to this type of projects..

design of Multi circuit transmission tower :

Quad circuit transmission towers are used in several transmission circuits in many parts of the world. Four nos. 3 phase circuits (12 conductors) are drawn on a single tower. It has some distinct benefits over double circuit towers. It occupies much less right of way space, it carries much more power than other type of towers, requirement of steel, civil and electrical materials are much less and easier to manage by the transmission agency. Disadvantage is that it cannot be used in voltage higher than 132kV.

Satcon, over the years, has developed capability to design these type of towers. The design and analysis is done by staad pro connect software and drawings are prepared by Revit software. 3D and 2D both type of drawings can be submitted. It is also possible to submit fabrication drawings and shop drawings of this type of towers..
