Analysis of new content of regulation on dam safety supervision of hydropower station by energy bureau

Clear responsibilities and strengthen supervision

Power safety supervision department is mainly responsible for the analysis of the " regulations" new content

On April 1, the state energy bureau drafted the " hydropower station dam operation safety supervision and management regulations" ( hereinafter referred to as the " regulations" ) by the national development and reform commission announced the implementation of decree No. twenty - third. Compared with the regulations on the safety management of dam operation of hydropower station ( hereinafter referred to as order No. 3 ) promulgated by the former state electricity regulatory commission in December 2004, what are the key aspects of the regulations that have been supplemented and revised? The main person in charge of the state energy bureau of electric power safety supervision department recently accepted the newspaper reporter interview, detailed analysis of the " regulations" new ideas

Revised focus on the scope of application is more clear, the main responsibility of enterprise safety more clear, dam expansion, reduction, retirement must be submitted for approval, scientific adjustment of regular inspection cycle, improve the safety registration system, clear regulatory responsibilities, strengthen legal responsibility

Compared with the original 3 orders, the " regulations" focus on the " scope of application", " operation management", " regular inspection" and other content to be revised.

A: yes, sir

In this regard, the state energy bureau of electricity safety supervision department, the relevant responsible person pointed out that in the past decade, China's rapid development of hydropower, hydropower investment diversification, " the original power system" concept has been difficult to define. In addition, in view of the hydropower station installed capacity and engineering scale and other factors determine its importance in the construction of national economy, according to the main functions of hydropower station, installed capacity and engineering scale to define the scope of application is reasonable and more clear.

A: yes, sir

At the same time, the regulations also further define the safety responsibility of professional technical services entrusted by the dam. It is reported that in recent years, some owners according to the concept of professional and market-oriented service management, their own dam management institutions, management personnel and technical personnel, dam safety related specific work entrusted to social service units to bear. This management mode is prone to unclear responsibilities, work is not in place. According to article 13 of the new " safety production law", the amendment in the " regulations" clearly in this case the dam safety responsibility is still borne by the entrusting party.

A: yes, sir Any change or adjustment of the function of the hydropower station, shall be reported to the relevant project approval ( or approval ) department for approval according to law. According to the reporter, in recent years, the hydropower station function change or adjustment, engineering transformation or expansion of the situation gradually increased, such as Zhejiang Fuchunjiang hydropower station lock expansion and transformation ( change the original lock function and part of the structure ), Guangxi lalang hydropower station expansion ( dam reconstruction power diversion water intake ) and other projects. The reduction of the project and the retirement of the dam are also gradually emerging.

By the end of 2014, of the dams registered by the national energy agency, 103 had been in operation for the longest period of time, and 30 had been in operation for more than 50 years. With the long-term operation of more and more dams, as well as the rapid development of society and economy, some of the dam, dam reinforcement treatment may be uneconomical, inappropriate or can be replaced by other means, scrapped, demolition or demolition and reconstruction of dam retirement cases will gradually appear.

" these new conditions and problems will inevitably change the dam safety management mode and the operation mode of the dam, and even cause permanent changes to the original structure of the dam, to a large extent, will affect the safety of dam operation. " the person in charge said," in this regard, according to the national development and reform commission decree No. 11 " government approved investment project management approach" requirements, the " regulations" clear, hydropower station function change or adjustment, engineering renovation or expansion, project reduction and dam retirement, shall be reported to the relevant project approval ( or approval ) department for approval. " in the" regular inspection " chapter," regulations " focus on clear dam safety regular inspection and special inspection of the overall requirements, clear the dam safety grade assessment standards, level and disease dam, risk dam processing requirements, the original electricity regulatory commission 3 orders article 19 of the requirements of the" regular inspection generally once every five years " is revised to" regular inspection generally every five years, inspection time is generally not more than one and a half years. After the first regular inspection, regular inspection interval can be dynamically adjusted according to the dam safety risk situation, but not less than three years or more than ten years ".

" this revision is intended to further reduce the burden on enterprises on the premise of dam safety risk control. The specific organization of regular inspection and special inspection work shall be implemented in accordance with the measures for the regular inspection of dam safety of hydropower stations. " said the head.

In the " registration" chapter, " regulations" article 24 clear " within the prescribed time limit does not apply for safety registration of the dam, shall not be put into operation, the generator set shall not be connected to the grid. " the general office of the state Council on the focus on the field of production safety" illegal " special action notice" clear " illegal" one of the key content is " undocumented, license is incomplete or expired, beyond the scope of the license to engage in production and business construction, and reselling, leasing, lending or in other forms of illegal transfer of safety production license", requires " the existence of illegal production and business construction units, shall be ordered to suspend production for rectification, and strictly implement the regulatory measures". Dam safety registration of hydropower station belongs to the " regulations on the administration of dam safety of reservoir" provisions of the administrative licensing examination and approval of the project, the dam of hydropower station is not in accordance with the provisions of the safety registration and generator grid generation belongs to the illegal production and operation, in accordance with the " general office of the state Council on the focus on the development of safety production in the field of" illegal " special action notice" requirements, shall suspend production for rectification. Grid - connected power generation is a specific form of hydropower station production and operation, the dam is not in accordance with the provisions of the safety registration of hydropower stations, the generator set should not be grid-connected power generation. In the actual work of dam operation safety supervision of hydropower station, there are a few dam operation management units regardless of the impact of dam operation safety on social and public safety, refused to register dam safety in accordance with the requirements. Therefore, in order to effectively promote the dam safety registration of the administrative licensing examination and approval work, to ensure the safety of dam operation and social public safety, the amendment refined and clear the " within the prescribed time limit does not apply for safety registration of the dam, shall not be put into operation, the generator set shall not be connected to the grid power generation" specific requirements.

A: yes, sir The original electricity regulatory commission promulgated the " regulations" of the dam operation safety management of hydropower station is not clear in the original electricity regulatory commission dispatched institutions ( after the reform for the state energy bureau dispatched institutions ) hydropower station dam operation safety supervision and management responsibilities. This amendment, the state energy bureau dispatched institutions dam operation safety supervision and management responsibilities to be supplemented, the state energy bureau dam safety supervision center responsibilities were improved.

In the chapter of " legal responsibility", according to the " safety production law", strengthen the power enterprises, professional and technical service units of legal responsibility, increase the dam operation safety management of illegal acts of punishment, and clear the legal responsibility of regulators.

New points after the dam water safety record, safety production bad credit records and " blacklist" system, other hydraulic structures safety management requirements

" on the new dam water storage safety appraisal will be related to safety information and safety management submitted to the state energy bureau of the dam center for the record, also belong to the new content. " the person in charge told reporters.

At present, from the actual situation of dam construction and operation, the dam after water storage to play the role of water retaining, water storage period dam safety incidents are prone to occur frequently. In order to strengthen the whole process of dam operation safety management and dam safety management construction period, operation period of convergence, specially added this content.

According to the requirements of the new " production safety law", the sixth chapter of the regulations in strengthening the power enterprises, professional and technical service units of legal responsibility at the same time, according to the safety Committee of the state Council on strengthening the construction of enterprise safety production integrity system guidance ", increased the power enterprises and technical service units dishonesty included in the safety production of bad credit records and safety production integrity" blacklist " of the relevant content.

The person in charge said that the " regulations" also added on the safety management of other hydraulic structures of hydropower station requirements.

It is reported that in 2009, Russia's sayan - shushensk hydropower station occurred " 75 people were killed, three units scrapped, serious damage to the plant" of a particularly serious accident. The accident shows that once the water conveyance tunnel, penstock and other water conveyance facilities and hydrogenerator unit of the hydropower station are crashed, the safety production of the power station and the public safety of the downstream society will be disastrous.

" therefore, the supplementary provisions on the safety management of other hydraulic structures of hydropower stations have been added in the supplementary provisions, and the electric power enterprises are required to carry out safety inspection and other management work on these equipment and facilities with reference to these provisions. " the head pointed out.
