What WTG SCADA does

Supervisory control for machines that never stand still

A wind turbine generator is a moving sensor platform: pitch and yaw motors reposition the rotor by the second, an anemometer and wind vane on the nacelle roof read the resource in real time, and a local PLC arbitrates it all against a torque and power curve set by the OEM.

SCADA is the layer that turns that per-turbine telemetry into a fleet you can actually run — polling controllers over the field network, normalising tags across vendors, raising alarms in priority order, and giving operators one set point interface instead of forty.

MD Infotech builds that layer: the historian, the alarm manager, the HMI, and the integration work that makes a mixed OEM fleet behave like a single asset.

Pitch & yaw

Blade angle and nacelle heading, actuated continuously to track wind direction and shed excess load.

SCADA historian

Time-series archive of every tag — wind speed, power, temperatures, alarms — kept for warranty and performance analysis.

Curtailment

A commanded power set point below the available curve, issued for grid, noise or shadow-flicker constraints.

IEC 61400-25

The communications standard that defines a common information model for wind power plant monitoring and control.

SLDC / RLDC real-time data sharing

Real-time data sharing with Tamil Nadu SLDC and SRLDC over IEC 60870‑5‑104

Grid-connected wind and solar plants have to stream real-time telemetry to the State or Regional Load Despatch Centre under the CEA connectivity standards and the Indian Electricity Grid Code. MD Infotech supplies its own SCADA/RTU, which reads the field directly and sends the values unprocessed, as the Tamil Nadu SLDC requires. We also map the signals, set up the main and standby links, and stay with the plant through end-to-end testing with the SLDC/RLDC until it is live.

Not sure your turbine is listed? MD Infotech's SCADA reads the turbine controller over MODBUS TCP/RTU, OPC‑UA, IEC 61400‑25 or the OEM's own protocol, so most makes and models can be added. The same platform also covers solar inverters and weather stations, and feeds real-time data to the Tamil Nadu SLDC or SRLDC over IEC 60870‑5‑104.

Beyond wind

Solar PV SCADA, on the same platform

The same historian, alarm manager and reporting stack extends to solar assets — inverter and string-level telemetry, weather-station data, and yield reporting alongside your wind fleet, or entirely on its own.

One shift desk, one alarm queue, one report, whatever the mix of turbines and arrays on site.

Solar SCADA details →

Inverter-level monitoring

DC/AC conversion efficiency, fault codes and daily yield tracked per inverter, polled alongside the wind fleet.

String & combiner monitoring

String-level current tracking catches a shaded or degraded panel string before it drags down an array.

Weather station integration

Performance ratio & yield reporting

PR, specific yield and availability reported on the same cadence as turbine KPIs.

Deployment sequence

FAQ

Common questions

What is WTG SCADA?

WTG (Wind Turbine Generator) SCADA is the supervisory control and data acquisition layer that polls each turbine's local PLC, normalises telemetry across vendors, and gives operators one alarm queue, historian and set-point interface instead of one per turbine.

Do you build SCADA for solar power plants too?

Yes. The same historian, alarm manager and reporting platform extends to solar PV assets — inverter and string-level monitoring, weather-station integration and yield reporting — alongside a wind fleet or entirely on its own.

Which turbine OEMs and PLC platforms do you support?

Suzlon, Siemens Gamesa (SGRE), Vestas, Leitwind, Kenersys, NEG Micon, RRB Energy and GE — see full fleet coverage above. Integration is read-only against the OEM controller, so the original PLC program is never modified.

Can you integrate third-party or legacy SCADA and PLC systems?

Yes. We bridge MODBUS TCP/RTU, OPC-UA and IEC 61400-25 into one tag set, including third-party SCADA platforms and older PLC-based turbine controllers, without altering the OEM's PLC program.

Do you provide analytics and reporting for renewable energy plants?

Yes — forecast-vs-actual output tracking, availability, capacity factor and performance-ratio reporting across wind and solar assets, built on the same historian used for monitoring.

Where is MD Infotech based, and which states do you serve?

MD Infotech is based in Tiruchirappalli, Tamil Nadu, and takes on wind and solar SCADA projects across Tamil Nadu and other states in India.

Can you connect our wind or solar plant to the SLDC or RLDC over IEC 60870-5-104?

Yes. We install the MD Infotech SCADA/RTU at the pooling substation, which sends unprocessed IEC 60870-5-104 data as the SLDC requires, map MW, MVAr, voltage, frequency, breaker status and met data to the point list agreed with the State or Regional Load Despatch Centre, set up main and standby communication links, and complete end-to-end testing with the LDC before go-live. See how the data path works.

Which turbine makes and models can share data with the SLDC?

All of them. Because the MD Infotech SCADA/RTU reads each turbine controller and meter directly, any make we provide SCADA for can report to the Tamil Nadu SLDC or SRLDC: Suzlon, Vestas, RRB, Siemens Gamesa, GE, Inox, Leitwind, Kenersys, NEG Micon, Enercon / Wind World, Senvion, Regen Powertech, Envision, Acciona, Nordex, Adani Wind, WinWinD, NEPC, Pioneer Wincon and Mitsubishi, plus solar inverters of any make.

How do wind farms in Tamil Nadu share real-time data with the Tamil Nadu SLDC?

The Tamil Nadu SLDC does not allow plants to process data before sending it, so an RTU reads the meters, breakers and turbine controllers directly. The MD Infotech SCADA/RTU at the pooling substation sends live, unprocessed MW, MVAr, voltage, frequency, breaker status and weather data to the Tamil Nadu State Load Despatch Centre (operated by TANTRANSCO) over a main fibre or MPLS link with a VSAT or 4G standby. MD Infotech supplies the SCADA/RTU, prepares the signal list in the SLDC format, sets up the links and completes end-to-end testing with the SLDC.

Can you share real-time data with SRLDC or other RLDCs?

Yes. Plants connected to the inter-state transmission system (ISTS) report directly to the Regional Load Despatch Centre, which for Tamil Nadu is the Southern Regional Load Despatch Centre (SRLDC). We set up the same IEC 60870-5-104 data path to the RLDC, and can feed both SLDC and RLDC where required.

Do you provide Suzlon SCADA?

Yes. We integrate Suzlon S64, S66, S82, S88 (all versions), S95, S97 (90 m and 120 m hub) and S111 and S120 turbines into one SCADA platform, read-only against the Suzlon controller.

Do you provide SCADA for Vestas, RRB, Siemens Gamesa, GE and Inox turbines?

Yes. We cover Vestas V47, V52, V66, V80, V90 and V100; RRB Energy V47 500 kW and 600 kW; Gamesa and Siemens Gamesa G52, G58, G8X, G90, G97, G114, G122 and G126; GE 1.5 ESS and 1.5xle; Inox DF 93.3, DF 100 and DF 113; plus Leitwind LTW77/LTW80, Kenersys K82, NEG Micon NM48, Enercon / Wind World E-40 to E-82, Senvion MM82/MM92/MM100, Regen Powertech Vensys, Envision, Acciona AW3000, Nordex, Adani Wind, WinWinD, NEPC, Pioneer Wincon and Mitsubishi.
