The opening of the era of parity highlights the importance of the "long-distance running" of photovoltaic power plants, and under the spotlight, photovoltaic operation and maintenance enterprises must eventually cross the jungle.

On May 22, the National Development and Reform Commission and the National Energy Administration issued the Notice on the Approval of Wind Power and Photovoltaic Power Generation Parity Projects in 2019, officially opening the era of photovoltaic parity in China. Under the new situation, more and more attention has been paid to the preservation and appreciation of stock assets, and enterprises have aimed at the field of intelligent operation and maintenance, and a series of operation and maintenance concepts and solutions such as intelligence and big data have appeared one after another. According to industry insiders, by the end of 2018, more than 100 enterprises across the country provided operation and maintenance services.

From the blue ocean to the red ocean, from products to services, from R&D to technology, return to the essence of value, how to help owners do a good job in operation and maintenance, and ensure the safe and stable operation of the whole life cycle of the power station? How to reduce costs and increase efficiency for owners is a problem that photovoltaic operation and maintenance enterprises must face, and it is also the key to building their core competitiveness.

Turning costs into benefits, intelligence + refinement is the core

For PV project owners, what they are concerned about is the investment income of the power station. A comprehensive O&M solution needs to focus on this core, which should not only focus on the investigation of abnormal power station conditions, regular inspection, ensure the normal operation of photovoltaic power plants, reduce the impact of power generation due to abnormal power station and equipment failure, but also pay attention to power plant operation, maintenance and asset management.

During SNEC in 2019, Hu Zhichao, deputy marketing director of Qingdao Sanas New Energy Technology Co., Ltd. (hereinafter referred to as "Sanas"), said that the foundation of everything is built on the safety of photovoltaic power plant assets. With the development of science and technology and the gradual arrival of intelligent equipment, photovoltaic operation and maintenance has shifted from the extensive development stage to the stage of intelligent and refined, and the stage of seeking benefits from the power station.

The so-called intelligence is an important embodiment of reducing costs and increasing efficiency. In the operation and maintenance costs, labor costs account for a proportion; And with the decline of the cost of photovoltaic electricity, the labor cost of the power station in the later stage has risen instead of falling, and how to save labor as much as possible in the stock and incremental projects has become the most important. Therefore, the Sanas O&M team has been thinking about how to improve work efficiency and reduce costs through technical means.

This is mainly reflected in two levels: first, intelligent operation and maintenance equipment, through the introduction of intelligent cleaning robots, drones and other hardware equipment services to reduce the workload and difficulty of operation and maintenance personnel. The second is to apply the intelligent monitoring system to promote the power station to achieve less people on duty, risk prediction, fault diagnosis and remote control, and timely elimination of shortages through big data mining and other methods. Especially in areas where power stations are concentrated, the centralized control system can fully control the operation and maintenance of power stations in the entire region, and send personnel to the scene to solve power station problems in a timely manner.

It is reported that after the comprehensive upgrade of the Sanas intelligent photovoltaic centralized control platform (SWS3.0), three major and more than 50 small functional innovations have been added, including the quality evaluation system of equipment and facilities of the whole station, the whole process of fault tracking module, regional irradiation comparison and irradiation/power generation evaluation system, etc., to achieve intelligent operation and maintenance.

In addition, regional management is an effective measure to solve the problems of uneven distribution of O&M personnel and resources. Specifically, based on the existing five regional operation and maintenance networks, Sanas has formed a three-level operation and maintenance monitoring and management, and the headquarters assumes the responsibility of leadership and supervision with a strategic vision; The regional positioning forms strong support and effective jurisdiction over the power station, forming a data center one by one, and comprehensively solving the pain points of scattered and difficult operation and maintenance of power stations.

In fact, the cost of PV operation and maintenance has been reduced to a few cents per watt, and in the era of low profits, it is more necessary to refine operation and maintenance management, improve the operation and maintenance efficiency of power plants, and provide value to customers.

O&M still needs to be standardized and needs to be standardized

With the increase of the operating life of photovoltaic power plants, the quality problems of photovoltaic power stations have begun to become prominent, especially the frequent failures of some photovoltaic power station equipment after the warranty and the closure of key equipment manufacturers, which have made operation and maintenance more and more difficult.

In addition, after the 5.31 New Deal last year, the operation and maintenance market has become the coveted cheese of many enterprises, forming a situation of competition between the three camps. First, system equipment manufacturers; second, third-party O&M providers such as Sanas; The third is other enterprises such as operation and maintenance equipment manufacturers, EPC integrators and so on. What follows is that some companies take advantage of various relationships, or in order to get projects regardless of cost, low-price competition and other chaos.

At present, the entire operation and maintenance industry still has not formed a standard, Hu Zhichao said, in this context, on the one hand, the operation and maintenance effect is worrying, on the other hand, it may cause the phenomenon of bad money driving out good money.

In order to cope with this situation, Sanas has developed its own operation and maintenance manual and management standards, and formed a set of management systems to standardize and quantify the behavior of operation and maintenance personnel. While reducing the risk of O&M personnel making mistakes and guiding the work of O&M personnel, it also reduces the work of O&M personnel to a certain extent.

For example, Sanas adopts intelligent power station equipment without blind spot data collection, surveillance video operation visualization. And the content of the inspection and the items of the inspection are included in the specification, and the operation and maintenance personnel take a standardized template to inspect, clarify the content of the inspection, and avoid omissions.

Be among the frontrunners

As a national photovoltaic technology leading base, Shanxi Changzhi Photovoltaic Technology Leading Base is one of the important demonstration projects for the country to promote the progress of photovoltaic power generation technology, industrial upgrading, market application and cost reduction. In mid-May, Sanas successfully became the operation and maintenance service provider of the new 250MW photovoltaic leader base project in Changzhi, Shanxi Province, fully demonstrating its technical centralized control capabilities and efficient service strength.

Talking about the operation and maintenance of the project, Hu Zhichao introduced that the Shanxi Changzhi 250MW photovoltaic "leader" base project is a super-large-scale power station, which brings higher difficult requirements to the operation and maintenance work, which involves high voltage level, large floor area, equipment and other problems, and the related management and maintenance work is more complex and complex.

Hu Zhichao further introduced, "After becoming the operation and maintenance provider of the project, Sanas will give priority to intervention from the construction stage of the power station according to the requirements, arrange personnel, and assist the owner to assist and supervise the construction of the power station from the perspective of operation and maintenance." Throughout the construction process, we ensure daily tracking and timely feedback. The pre-operation and maintenance is conducive to ensuring the safe operation of the power station in the later stage of the life cycle of up to 25 years, and reducing the difficulty of shortages and operation and maintenance in the later stage. ”

Specifically, the pre-operation and maintenance work of Sanas will focus on three aspects: tracking the adjustment suggestions of the construction design, the synchronous elimination of defects in the construction stage, and the formulation of exclusive operation and maintenance plans.

More than "leading", Sanas has deeper expectations for the field of photovoltaic operation and maintenance. 25 years - Value's management plan for the whole process of renewable energy operation and maintenance; Cross-border VR integrates intelligence into team training, and Sanas's appearance during this SNEC is particularly dazzling. The former is Sanas' responsibility to the customer; The latter is Sanas's dedication to the team.

Using VR technology as the medium, combined with Sanas's rich training knowledge system, it can effectively avoid power safety risks and provide immersive high-simulation power station skills training, so as to improve the practical ability of front-line personnel, shorten the training cycle of talents, and quickly improve teamwork.

Up to now, Sanas, as a new energy digital technology management and control service provider, has served more than 3.8GW of power station capacity, forming a full life cycle management system of photovoltaic power plants, covering photovoltaic power station site selection, power station equipment selection, power station construction links and monitoring, inspection and maintenance after the completion of the power station, etc., through online and offline linkage mode, power station management.

Its O&M service network covers 29 provinces and cities including Shandong, Shaanxi, Ningxia, Inner Mongolia, Anhui and Henan, and its partners include listed companies, energy giants and multinational enterprises, and its service types cover ground power stations, agriculture (fishery) and photovoltaic complementation, rooftop distributed and photovoltaic poverty alleviation.

While the domestic business is progressing steadily, Sanas has signed a contract with Pangwo Power to provide technical services for the 60MW photovoltaic power plant in Malaysia, and Sanas is practicing the strategy of diversified business globalization.

Don't forget the original intention, you have to always. With the further integration of digital information technologies such as artificial intelligence, big data, and cloud computing into the photovoltaic industry, Sanas will adhere to the value of power stations and continuously improve its service capabilities, and the future is promising.
