Mandatory Additional Facilities | Alternate Module Cleaning – 1

Concept

Availability of water supply in the solar parknot sufficient for efficient cleaning of solarpanels by water manually.

Adequate water supply will always be aconstraint in the desert region.

This will lead to higher soiling losses in thesolar plant, less efficient plants means loss ofrevenue.

Hence, alternate cleaning technologies needto be explored which provides efficientautomated cleaning without the dependencyon water.

31

CEA Regulation on Connectivity – Draft 

Regulations applicable for solar projects connected after 6 months of CEA final regulations.

Introduction of LVRT for solar generators – Generators to continue generating active power proportion to rated voltage during system voltage dips up to 15% for 300 ms till it reaches 85%

between 300 ms to 3 sec. Maximise reactive power till voltage starts recovering till 300 ms.

Introduction of HVRT for solar generators – Generators to remain connectedunder high voltage scenario ‐

Introduction of Frequency range for solar projects to respond For frequency variation <0.3 Hz – generator response (addl. real power) proportional to frequency deviation For frequency variation >0.3 Hz – generator required to provide immediate real power frequency response of

10% of maximum active power capacity within 1 sec. In case Energy storage systems used, during frequency below 49.7 Hz, generator frequency response to act

within 1 sec and to be maintained at least 10 min. Further, ramp rate control tolerance to be ±10%

Optional Solar Park Facilities | Master Control Center – 2

CEA Regulation on Connectivity – Draft 

Introduction of voltage regulation services – Generator to have a continuously variable, continuously acting, closed loop control Voltage Regulation System

(VRS) like AVR VRS set point should be adjustable in a range prescribed by SERC and by SLDC via SCADA VRS controller strategy to be based on Proportional plus Integral control actions with parallel reactive droop

compensation VRS to be calibrated such that change in reactive power will achieve 95% of its final value no later than 1 sec

with step change in voltage VRS to be in service as long as generator connected to grid irrespective of MW output including Nil generation VRS dead band not to exceed ±0.1%

Review of harmonics limits – Limits of voltage/current harmonics, point of harmonics measurement, method of harmonics measurement to

be in accordance with IEEE 519‐2014 standards Measuring & metering of harmonics shall be a continuous process with permanent meters complying to IEC

61000‐4‐30 class A capable of detecting direction of harmonics Measurement of power quality parameters voltage sag, swell, disruptions to be done every month

38

Optional Solar Park Facilities | Master Control Center – 3

Concept

Utilities to approve connectivity only pursuantto compliance to CEA Regulations

The concept is to have all the control &monitoring stations at one central location.

Monitoring and Control Work Stations shall beprovided to individual SPDs in one centrallocation having all the feeds from the solarpark (Eg. Weather Data, Battery StorageControl, Forecasting & Scheduling andInterface with SLDC/RLDC)

This helps in smooth interface management ofthe solar plants and as well as with Grid(STU/CTU), SLDC/RLDC.

39

Optional Solar Park Facilities | Master Control Center – 4Feature Details

Master Control Center (MCC)

MCC would be compatible with CEA Guidelines of Technical Standards for Connectivity to the GridRegulations, 2007 and its amendments and subsequent modifications.

Relationship Saurya Urja shall facilitate the technology selection, vendor arrangement/management,

implementation and maintenance on the site at Master Control Center. SPD shall be responsible for initial upfront charges and fulfilling the installation requirements.

Intended Benefits

Monitoring & Controlling of all plant SCADA from one location – regulation of Inverter Generation tomaintain Load‐Generation balance as per the requirements of Regulator/RLDC/SLDC.

SPDs do not have to interface with Regulators/RLDC/SLDC directly. Capex & Opex Savings and faster commissioning as Cost of Control Room and SCADA to SPDs

eliminated. Integrated yet scalable system. Single point management and single Database.

Next Steps Saurya Urja would carry out the above work provided all SPDs express interest. Charges to beintimated separately.
