Grandsun participated in the InternationalGreen Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to 30 (Fri) andintroduced its monitoring system needed for maintenance of power generators.

Grandsun’s integrated monitoring system isan efficient and stable customized solution which applied smart operationfunctions. Users can control solar power generation facilities, suggestsolutions from system failures, and provide a report through step-by-stepanalysis of the efficiency (operation, conversion) for each inverter.

The data detected in the switchboard,transformer, inverter, and connection panel can be checked in real time, andquick actions can be taken in case of a problem. Also, the company willintroduce a control system to extinguish fire at the initial stage by sprayingsolid aerosols when detecting flame, heat, and temperature sensors in powergeneration facilities such as junction panels and electric transmission facilities(ACB, VCB). Also, it is possible to check the construction progress in realtime through a mobile phone app or PC by installing FHD quality CCTV in thepower plant.

At the Green Energy Expo exhibition hall,AVING News met Grandsun’s Chief Researcher Song Eun-ki to interview on themonitoring system.

Q1. Company introduction

A. Song: Grandsun was established in 2005and has been running the solar power generation business for 16 years. It isalso participating in government support projects, and has been in relationshipwith the Korea Energy Agency for seven consecutive years. It operatesapproximately 350MKW generated from 15,000 power plants.

Q2. Reason for developing monitoring system

A. Song: We are introducing a monitoringsystem for solar power plant management and safety. Since we have been in thephotovoltaic power generation business for about 16 years, I think weunderstand the needs of the market better than anyone else. We have beendeveloping the monitoring sector by determining that what customers need ismonitoring system.

Q3. Overview of monitoring system

A. Song: In this exhibition, fourmonitoring systems were introduced. First, HMI Control Monitoring can be usedfor safety, control and monitoring, and can be used in large-scale powerplants. Second, the GS REMS Program is a small and medium-sized monitoringsystem that allows individual operators to easily check the contents with asmartphone app. Third, Optimizer Monitoring is a system that can solve factorsthat hinder generator operation and control. And finally, Integrated Monitoringis a system that can manage the programs mentioned previously.

Q4. What are the reactions from the participants?

A. Song: We participated in the GreenEnergy Expo for the second time after last year. Certainly, the response of thevisitors was positive, and it could be seen that the degree of interest hasincreased compared to the past. Especially, there was a lot of interest fromindividual customers regarding the newly launched monitoring system, but mostof all, business-related contractors and maintenance companies gave a lot ofinquiries.

The 18th International Green Energy Expo isKorea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewableenergy exhibitions, and the only exhibition jointly organized by the four majorassociations. The exhibition covers △Solar power △ESS (energy storage system)& battery △Smart grid technology △Wind power and △New and renewable energy.This exhibition is hosted by Daegu Metropolitan City and Gyeongsangbuk-do andorganized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
