SPECIFICATION FOR GRID CONNECT SOLAR GENERATING SYSTEM OF CAPACITY 10 KWp TO 500 KWp

1.0 FOREWORD:

Government of India is laying great emphasis on reducing the country’s carbon footprint. In this pursuance, the Hon’ble Prime Minister of India

has on 30th June, 2008 released the National Action Plan for Climate Change (NAPCC). One of the NAPCC missions is the National Solar Mission and it aims to increase the share of solar energy in India’s overall energy mix. Accordingly, Indian Railways accords high priority to harnessing of solar energy.

The energy generated by grid connect solar photovoltaic system will be

utilized to feed railways’ electrical loads during daytime. As a result, during daytime, the purchase of electricity from the electricity authority will get reduced.

2.0 SCOPE:

This specification provides the generic requirement for grid connect solar photovoltaic (SPV) system capacities in the range 10 KWp to 500

KWp. The user will specify the SPV system’s KWp capacity, after duly considering the MNRE norms for subsidy, electrical load and availability of space for installation of SPV modules. In instances where none of the

standard available Power conditioning unit (PCU) KVA ratingsare commensurate with the purchaser specified KWp of SPV system, in

such case the purchaser can consider accepting the PCU of next higher standard rating.

The specification covers general and technical requirements for design, manufacturing, testing, supply, installation and commissioning of Grid connect solar generating system to be provided at railway premises for

meeting the railway requirements of lighting, ventilation and other electrical services. The solar photovoltaic generating system’s inverter

will operate in parallel with the general electric supply system on railway premises.

4.0 SYSTEM DESCRIPTION:

4.1 Solar Photovoltaic (SPV) grid connect system shall consist of mainly the following: -

i) Solar panels

ii) Module mounting structure

iii) Junction boxes

iv) Power conditioning unit (PCU)

v) Import & Export metering

vi) Cable and other accessories

4.2 The PV array converts the light energy of the sun to DC power. The module mounting structure shall be used to hold the module in position. The DC power shall be converted to AC by PCU to supply AC

loads such as computers, lights, fans, etc. within the railway premises. Solar power shall be integrated with the premises power supply from

electricity authority.

of 61


4.3 DC distribution board/ combiner shall be provided in between solar array and PCU. It shall have DC Disconnector/MCCB of suitable rating

for connection and disconnection of array section. Type II Surge Arrestor should be incorporated for surge protection. It shall have

meters for measuring the array voltage and array current. Appropriate IP protection shall be provided. In case of string inverters, if the requirements served by DC distribution board are fully taken care of by

string inverter(s), then firms’ proposal (if any) for elimination of DC distribution board from the system design, can be considered.

4.4 AC distribution board shall be provided in between PCU and loads. It shall have an integrated energy meter, voltmeter and ammeter. As for

energy, generally the parameter of interest shall be the aggregate energy output of inverter(s) fed into the individual AC distribution board(s). Though not mandatory, firms are however encouraged to also offer the

facility for recording the energy output data of each inverter (wherever multiple inverters are feeding into an AC distribution board). Class I + II (as per IEC 62305) 100 kA Surge Arrestor should be incorporated for

protection against surges.

4.5 No electrical storage batteries shall be required and accordingly, these are not included in the scope of work.

4.6 The system shall comply IEC 60364-7-712 and 62446.

5.0 GENERAL REQUIREMENTS: 5.1 Solar generating system shall supply part/ full load of railway service

buildings/ areas. Thereby, the PV system shall reduce the electric energy units drawn by railway from the grid and reduce IR’s CO2 emissions.

5.2 Solar panels and array junction boxes shall be installed on shade free

roof while the transformer based PCU and distribution boards, etc. shall be housed inside the room provided by Railways. In case of string inverters, railways should carefully weigh the option of indoor vs.

outdoor installation. The installation of SPV modules on roof-tops must not impact the waterproofing of the existing terrace structure. The

contractor shall be responsible for restoring the waterproofing to its original condition and for provision of additional waterproofing in the areas where RCC blocks are secured on to the terrace. Even though

roof-top mounting of solar panels shall be the preferred option, if necessary, railways can at their option specify a ground mounted solar system for part or full system KWp capacity. In the event that railways

decide on a ground mounted solar system, they must specifically mention this in their tender and also specify the fencing requirements

as will be appropriate to the site (ref. item 6 of Annexure - C). For ground mounted solar systems, railways may need to: carry out site preparation works (e.g. site levelling, removal of obstructions, etc.); plan

of 61


suitable arrangements for preventing theft, vandalism, etc.; ensure the availability of adequate railway base load; identify a reliable railway grid

power supply line and be responsible for carrying out any supplementary works required for feeding the renewable energy into the

identified railway grid power supply line.

5.3 For individual systems above 20KWp, availability of requisite space on a

single roof-top can at times become a constraint. In such case, the system’s overall KWp capacity can be distributed across multiple roof-tops and each of the rooftops shall then feed to the grid power supply

system. In works involving such distributed systems, the purchaser must mention the KWp of individual constituent solar systems in the

tender (refer item 7 of Annexure - C). If the purchaser doesnot mention anything against item 7 of Annexure - C, it will be deemed that adequate space is available on a single rooftop for the entire KWp

capacity of the system.

5.4 If required, statutory approval of local authorities/state electricity

distribution company, etc. shall be obtained by the Railway Authority. An export meter (for recording the number of units exported to the grid),

if required, shall be either installed by state electricity distribution company or else the respective Railway Authority may include the same in their scope of work. Export metering will be an optional item; it will

be specifically mentioned by purchaser, if the same is required to be within the contractor’s scope of supply (see Annex C item 5). It is

emphasized here, that primary purpose of installing the SPV system covered by this spec., is to meet railway’s own energy requirement, rather than supplying renewable energy to the public grid.

5.5 Railway Authority shall provide a shadow free area @ 125 - 150 sq.

ft./KWp of solar array.

5.6 Array structure of PV yard and all electrical equipments such as PCU,

inverters, etc. shall be grounded properly. Towards this end, the contractor will supply and install an adequate number and appropriate size of IS:3043 – 1987 compliant earthing kits; at least one each for AC

circuit, DC circuit and lighting protection system.

5.7 Suitable marking shall be provided on the bus for easy identification.

5.8 PV modules may be connected in series up to the maximum allowed

operating voltage of the PV modules and the PV inverter, whichever is lower.

5.9 The reverse current of blocking diodes (connected in series), if required/ provided, shall be rated for 2 X VOC STC of the PV string.

5.10 Proper sealing arrangements at the points of cables entering the

enclosures/ buildings should be incorporated. Although not mandatory,

of 61


manufacturers are however encouraged that the cables entering into the enclosures be sealed with modular EPDM based cable sealing and

protection system based on multi-diameter technology.

6.0 TECHNICAL REQUIREMENTS: 6.1 The DC output from the modules shall be fed to array junction box

and the strings are paralleled at sub Main & Main junction boxes. Then PCU shall convert DC energy produced by the solar array to AC energy. The AC power output of the inverter shall be fed to the AC

distribution board (metering panel & isolation panel), which also houses the energy meter. The AC output of grid-connect SPV system should be

paralleled with railway’s general electric power supply i.e.the power supply received from the electricity authority.

6.2 The system shall automatically wake-up in the morning and supply power, provided there is sufficient solar energy and the grid voltage and frequency are in range.

6.3 When the grid voltage and/or frequency go out of preset range, the

inverter shall be immediately disconnected from the grid. The inverter will reconnect after a pre-determined time when the grid is back in the range.

6.4 Array to inverter voltage drop shall be less than 3% at the maximum

power output of the array. 6.5 Railways shall provide adequate space and ventilation for the inverter. If

string inverters are used, thesecan be installed below the solar array.

6.6 For safety reasons, PV inverter system shall be disconnected from the

network following a fault or loss of supply on the power network.

6.7 The performance and generation data shall be recorded using a data logger. The monitoring system shall comprise of the following main components:

6.7.1 PCU will log the inverter performance data and transmit the same to the

data logger. It shall also monitor basic parameters like power generated, etc.

6.7.2 Data logger shall gather information and monitor the performance of the inverter. It shall also support measurements from the external sensors. Data Logger shall also monitor the Solar Insolation and Temp

of Array Yard. RDSO and the concerned railway shall be afforded free of cost facility for viewing the system performance data on the

manufacturer’s or system integrator’s or railway’s web portal for until the contractual warranty period of the system. It is advisable that the facility of web based system monitoring should continue even after

of 61


completion of warranty period. After the warranty period, the web based monitoring facility shall be available as a part of AMC, if any (see Cl.

12.0). Else, if the railway desires to enter into a separate new agreement with the contractor solely for post-warranty web based monitoring for a

specified period, then it should provide for the same in special condition of tender and ask the tenderers to quote for the same (refer item 8 of Annexure-C).

6.7.3 Data logging system/software shall enable automatic long-term

storage of measured data from PV plant. It shall allow visualization,

monitoring, commissioning and service of the installation. The data logger shall be web enabled. It should be possible to access the data

logger with any standard web browser like internet explorer, google chrome, etc. and for this purpose, relevant software/ hardware will be supplied by the contractor. In addition to the web portal, it should also

be possible to retrieve the data directly from the data logger. The software for access/ visualization of data from data logger should also be provided by the supplier. Necessary executable files, if any, will be

required to be given free of cost by the supplier on a CD/ any other storage device.

6.7.4 Communication interface

The system should offer RS232/RS485 port and LAN/ WAN interface to facilitate remote monitoring of the system.

6.8 Sizing of the SPV system

Sizing of the system should be decided on the basis of railway’s

electrical load requirement and the availability of space for installation of SPV system.

6.9 SPV Module
