The Accident at Reftinskaya GRES has become a serious test for the entire energy system of our country. Until now, the representatives of the Commission, established to investigate its causes, can not give a definite answer about the causes of this incident.

The investigation was conducted by such agencies as the Ministry of energy, Rostekhnadzor and the Federal. The investigation of the accident at Reftinskaya GRES carried out and journalists visiting the scene of the tragedy, after talking with the management of the station, and after hearing the opinion of independent experts.

Tragedy at the station

The Fire, which occurred on August 22 of the current year at two o'clock, was the result of a splash of molten metal. In Reftinsky power plant accident due to the destruction of the insulator. Such a statement sounded as if no tragedy was life at the station is in normal mode.

Department of energy

The Most complete version of what happened was the information provided by the Ministry of energy of the Russian Federation. The accident at the Reftinskaya GRES is considered as the cause of the destruction of the capacitor a high-voltage line (220 kV). The result was the release of oil, lost during a fire section tyres. The station was a reduced capacity with the maximum score (2295 MW) to the zero parameter.

Consequences of loss of power

The accident at Reftinskaya GRES led to momentary operation of the automatic protection systems. All the high voltage lines that go from the station, passed out. Reftinskaya GRES (CAS 2016, to be precise) has led to many of the cascading outages across the country.

Experts

Arguing about what the accident occurred at Reftinskaya GRES, the experts agree that this is one of the largest technogenic disasters in the former Soviet Union.

As the primary causes of the incident large-scale shocks they called a coupling capacitor. This rod length of two meters, having an insulating ceramic ring inside contained the melted butter.

Accurate information about explode if the capacitor have no experts, but in it the main causes of the accident at Reftinskaya GRES. The work of the experts continues, are other possible causes of the fire at the station.

Locals

The Inhabitants of the nearest village of Reftinskaya learned from his relatives that the accident occurred at Reftinskaya GRES. Photos of the damage, they saw only in the papers. When journalists arrived in these places to conduct their own independent investigations, began to ask the inhabitants of the area about the tragedy, they all, without hesitation, replied that an explosion occurred in oil capacitor. Such unanimity has caused members of the press doubt, they decided to go to the scene.

Investigative Journalism

Many local residents watched the sparks from the electric arc, as there is a short circuit on next to each other the sections of wire. People say that the impression, as if the whole sky was filled with sparks.

This is proof of how serious was the accident at Reftinskaya GRES. Photo taken right after the tragedy, confirm the scale of the tragedy. The journalists, who conducted their independent investigation, failed to take a picture of the consequences of the accident.

Representatives of the security service of Reftinskaya GRES told the press that this plant is a strategic object, so any photos and videos is prohibited. After the intervention in the current situation press service of PJSC “Enel Russia”, direct of the owner of this power plant was able to resolve a conflict situation.

After ascertaining the identity of reporters, the head of the security service station gave permission to photograph the scene of the accident. These shots were published, attracted the attention of Russian ecologists. Residents of the village of Reftinskaya think they just got lucky. If the station does notprotection system triggered, the consequences of the accident would have been much bigger.

In an interview Oleg Kozmeniuk, holding the position of Deputy General Director of “Enel Russia”, noted that immediately after he received information about the accident, he flew to Yekaterinburg. According to his version, on the open switchgear, designed for 220 kW, emerged the complete destruction of the coupling capacitor.

As a result of that, there was a short circuit that spread to the tyres, designed for 220 kW. At the time of the tragedy in full work there were six energy units.

Thanks to modern automated systems of protection available on the station after triggering technological lock managed to gradually turn off all units. Such actions were eliminated any possibility of the continuation of the accident.

Situation at the station currently

System operator was given the request to activate in normal mode all eight power units. Just a few days after the tragedy restored operation of the sixth block then back to a normal schedule the second block.

By Wednesday 24 August, the station was restored to its original mode of operation. Thanks to the coordinated work of professional engineers, managed in a minimal time frame to cope with the emergency.

Professionals

Engineers answer carefully the questions of the journalists about whether it could happen more serious and powerful explosion, if not for the professionalism and automation of the station. They told the press that it is always ready for any emergency situations and work on creation of complete system of measures aimed at improving protection of the station.

Safety first

Special attention is paid to continuous staff training, emergency response drills. During these sessions modeled various problematic situations, allowing staff to improve their practical skills, to deal with the behavior in the event of an emergency.

After the end of the training be sure to understand the actions of every employee of the station, analyzed all the flaws, so that next time they were not retried.

Experts say that thanks to the coordinated work of the station personnel were able to quickly cope with the emergency situation, to prevent casualties. In the course of the investigation, the reporters found that in September 2000, the emergency situation has happened at Reftinskaya GRES.

The station Staff confirmed this fact and noted that in both cases taken to address the serious consequences was the landing station to the zero phase, i.e. disconnecting the power supply.

That's why all the training operating staff systematically carried out by specialists on labor protection, relate to the actions of employees in case of emergency in this scenario.

Conclusion

One version of the accident, consider various expert commissions, were the unusually high temperatures prevailing during that period in the region. A direct answer to the existing relationship between the exploded capacitor and the abnormal temperature in the course of the investigation have not been identified.

The Experts having understanding of the operation of such equipment claim that as one of the causes of the emergency can be a latent defect (the marriage of equipment), as well as improper use, defective Assembly plants. Experts explain that during the installation of the power equipment this class mostly attract third-party organizations.

Due To the fact that the warranty period has ended, it will be difficult to bring them to justice. Experts also noted the need for systematic monitoring of plant status and the appropriateness of timely maintenance.

Energy specialists don't exclude the possibility of negative impact on the normal operation of the capacitors abnormally high temperature. They are convinced that natural conditions could be an additional factor that, together with human resource led to the emergency situation. Its position they explain on the basis of a high school course in physics. During heating, the expansion of oil can cause an explosion.

Its position on the tragedy, its consequences for wildlife have not yet voiced by the environmentalists. They continue to analyze changes observed in the region to assess the seriousness of the accident at the power plant. The investigation of the accident at the Reftinskaya GRES is ongoing.
