Sumitomo electric industrial co., LTD (head office: Osaka central region;President: inoue cure;Hereinafter referred to as the company), development and sales of series PLC group * creates monitoring device, for the first time as upgrading the product adopted by solar power plants.

A fixed price on renewable energy acquisition system (FIT) * squared shortly after the start operation of solar power stations, more than 10 years, the situation of the need to be maintained on a large scale is increasing.At the same time, used to monitor the state of the power generation group series monitoring device also failed and aging, to update the device demand is growing.But, some existing device can't be a single equipment update, have no the same manufacturer's successor, or even influence the stable operation of solar power station situation happened.

So far, the company's 1000 v series PLC group monitoring device as a new and additional equipment import list of monitoring device of solar power stations, won the customer's use.This product can also be used for upgrading of products, so the device in solar power station replacing different company produces the monitoring device has been used for the first time.Here's why.

(1) using the easy to install the additional structure (package current sensor of the jacket).
(2) the miniaturization design, save a space, can be installed in the junction box installed).
(3) by using the powerline Communication lines of the PLC (Power Line Communication) technology.
　传统电力线也可导入该装置，因此无需架设通信线路，可降低导入成本（根据本公司计算，与其它方式相比可降低70%）。同时，因该装置使用有线通信，数据传输具有稳定性。此外，该装置内不会发生电位差，所以雷电流反击的可能性为零。

Are expected series PLC group monitoring device of the market demand will be increasing.Solar power station will promote the goal of carbon neutral, are getting social broad attention, in order to ensure the efficient and stable operation of the solar power station, the company will continue to provide high convenience PLC monitoring device and the supplementary services.


S reference
【 the company solar power station special characteristics of monitoring device of PLC group 】
1. Each group can be continuous monitoring, early detection of abnormality, convenient to take countermeasures
Units of power regulator solar power station monitor, unless the effect of the abnormal situation reaches a certain level, otherwise cannot be detected, but the company can system to monitor each group list, and can monitor showed significant change in power regulator before detect anomalies.Early detection is unusual, can take countermeasures as early as possible.

2. The automatic identification of monitoring data and fault through the analysis of the AI content
Since November 2019, the company launched a service, through the analysis of the AI group PLC series monitoring device the collected data, and provides the daily, monthly and annual reports.AI can automatically identify the fault content and inform the fault location, for the use of accurate and efficient management support and maintain the tally.By importing this service, can reduce the tally the amount of work on a regular basis.

* 1 group PLC (power line communication) series: be used for power line communication line technology, suitable for array connection of solar panels.This company product USES the low frequency of PLC technology, the use of frequency, 450 KHZ and below string current measurement data set to overlay on the direct current (DC).

* 2 power company in line with the requirement of the system have a duty to price set in a certain period of time to purchase the use of solar and other renewable energy to generate electricity.
