Grandsun participated in the International Green Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to 30 (Fri) and introduced its monitoring system needed for maintenance of power generators.
Grandsun’s integrated monitoring system is an efficient and stable customized solution which applied smart operation functions. Users can control solar power generation facilities, suggest solutions from system failures, and provide a report through step-by-step analysis 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, and quick actions can be taken in case of a problem. Also, the company will introduce a control system to extinguish fire at the initial stage by spraying solid aerosols when detecting flame, heat, and temperature sensors in power generation facilities such as junction panels and electric transmission facilities (ACB, VCB). Also, it is possible to check the construction progress in real time through a mobile phone app or PC by installing FHD quality CCTV in the power plant.
At the Green Energy Expo exhibition hall, AVING News met Grandsun’s Chief Researcher Song Eun-ki to interview on the monitoring system.
Q1. Company introduction
A. Song: Grandsun was established in 2005 and has been running the solar power generation business for 16 years. It is also participating in government support projects, and has been in relationship with the Korea Energy Agency for seven consecutive years. It operates approximately 350MKW generated from 15,000 power plants.
Q2. Reason for developing monitoring system
A. Song: We are introducing a monitoring system for solar power plant management and safety. Since we have been in the photovoltaic power generation business for about 16 years, I think we understand the needs of the market better than anyone else. We have been developing the monitoring sector by determining that what customers need is monitoring system.
Q3. Overview of monitoring system
A. Song: In this exhibition, four monitoring systems were introduced. First, HMI Control Monitoring can be used for safety, control and monitoring, and can be used in large-scale power plants. Second, the GS REMS Program is a small and medium-sized monitoring system that allows individual operators to easily check the contents with a smartphone app. Third, Optimizer Monitoring is a system that can solve factors that hinder generator operation and control. And finally, Integrated Monitoring is a system that can manage the programs mentioned previously.
Q4. What are the reactions from the participants?
A. Song: We participated in the Green Energy Expo for the second time after last year. Certainly, the response of the visitors was positive, and it could be seen that the degree of interest has increased compared to the past. Especially, there was a lot of interest from individual customers regarding the newly launched monitoring system, but most of all, business-related contractors and maintenance companies gave a lot of inquiries.
The 18th International Green Energy Expo is Korea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewable energy exhibitions, and the only exhibition jointly organized by the four major associations. 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 and organized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
