Smart Solar Pv Solution.

Smart Solar Pv Solution.

Introduction

Smart pv solution is combination of modernize digital technology with simple smart & global operation and management techniques.

It’s incorporates power conversion, remote control, data collection, online analysis as well as environment adoption etc.

  • Why we need smart pv solution?

We need smart pv solution to achieve efficient power generation, smart O&M, maximum reliability & safety and maximize ROI.

  • From solar plant construction to O&M we have to optimizes & innovate entire process, how?

To optimizes & innovate entire process, we have to integrate 3 technology, Pv technology, information technology and internet technology.

By using these technologies we can able to reduce the O&M cost, optimize initial investment, raise the energy yield as well as increase ROI.

The smart pv solution also includes high speed interconnected networks to provide real time solar plant information. We may use ANN, cloud storage as well as big data analysis to process the smart information for solar plant management and continuous optimization of solar plant performance.

Smart Pv Technical Solution.

While we designing any project two things we must keep in mind is performance ratio & internal rate of returns (IRR) of our project.

  • How we increased IRR and PR by using Smart Pv Technical Solution?

We increased IRR and PR by using modernizes & advance digital technology as given below,

  • Multi MPPT Controller,
  • Multi peak tracking (ANN),
  • separately dividing Pv module string,
  • By analyzing losses, shading effect, terrain inconsistency etc.

If we use Multi-MPPTs and Multi peak Tracking system we get higher energy yield.

Smart string monitoring with better availability during faulty condition.

Currently we are using DC combiner cabinet with lower MPPT controller, instead of using this technology we have to use smart Pv controller. It’s combination of MPPT & Inverter.  Smart Pv controller is control center in solar power plant. Using smart Pv controller we can detect both current and voltage of each string.

So that it’s increased accuracy for fault detection in minimal time period and increased efficacy of O&M.

For example ~ approximately few year ago we us only two MPPT controller for 1MW, but now we have to used 100 MPPTs controller for a 1MW plant.

The distribution system we connect in series connection, due to this if in any of the component fault occur then whole s/m may fail, Instead of using distributed parallel s/m, the failure rate may reduce because,

  • If we use multiple Pv controller out of this, if one controller fails, no effect on other controller because it’s connected in series.
  • If fault occur it’s easy to reinstall because it’s small and light in weight.
  • As it’s available in spare and easy to reinstall, it’s reduce the chances of failure rate.

The smart pv controller support software, it can remotely upgrade online to adopt changes of component and environment.

Smart & efficient O&M with Expert O&M system and big data analysis.

As we know the only field engineer can’t able to provide accurate & real time data of O&M. there for we need smart technical solution as given below,

  • Use SCADA or Drones to conduct large scale inspection of O&M performance of any particular solar power plant. It’s providing you smart communication or interaction channel with real time data to Field engineer to head office.
  • It’s optimizes the allocation of personnel and improves the mountainous efficiency.
  • Big data mining & expert s/m is an platform based on the cloud stroage, big data mining and expert s/m. this allows user to customize reports and perform secondary development.
  • Expert O&M system and big data analysis also provide maintanance and check-up suggestion to increase ROI.

System safety & PID effect prevention.

As safe DC transmission & protection are key & difficult issue, Smart Pv S/m is free of dc combiner cabinet, the DC power from Pv string s directed to Smart Pv Controller for converting into AC power & long distance transmission.

It measures such ac reducing length of DC power cable & removing  DC combiner and prevents DC transmission safety and protection issue.

To preventing PID effect we use plc based RCD ckt for safety against leakage current and provide highest safety to human being.
