Policy Interpretation of "Several Provisions on Safety Management of Electric Power Secondary Systems"

As the largest and most complex industrial control system, the power secondary system is an indispensable and important part of the power system and an important line of defense to ensure the safe and stable operation of the power system. Since the "Regulations" were issued in 2011, they have played an important role in ensuring the safe and stable operation of the power system. In recent years, the structure of the power system has become increasingly complex, dispatch objects have become more diverse, control objects have grown rapidly, and network boundaries have expanded. Compared with the 2011 version of the Regulations, the safety management situation of the secondary power system has changed significantly. The newly revised "Regulations" focus on all aspects of power secondary system safety management, and divide the full text into five chapters: general principles, planning and construction management, operation and maintenance management, setting values ​​and parameter management, and supplementary provisions, explaining the formulation of the "Regulations" The purpose and basis, scope of application, management responsibilities and overall principles stipulate the relevant requirements for all relevant units to carry out the planning and design of the power secondary system, equipment selection, installation and acceptance, etc., and clarify the daily maintenance, update and transformation, faults, etc. of the secondary system. The work regulations on disposal and other aspects put forward the requirements for fixed value and parameter management.

In this revision, the technical supervision responsibilities of the dispatching agency are further clarified, a written reporting system for secondary system safety management is established, and new energy (including intermittent power supply) power generation is established< a href="https://www.gkzhan.com/chanpin-t4301.html" target="_blank">Control systems, DC control and protection systems, etc. are included in the scope of power secondary systems, expanding the "Regulations" The scope of application has added new requirements for the network security protection of power secondary systems, and added requirements for strengthening network security monitoring and incident information reporting, and is in line with the country's newly issued network security-related laws and regulations. It merges the parameter management content of generator excitation speed regulation, new energy and other related power generation enterprises, refines the data configuration and operation mode management requirements of power communication equipment, and adds the parameter configuration management and filing content of the dispatch data network.

In the next step, the National Energy Administration will actively carry out follow-up work such as policy publicity and implementation and system connection. Dispatching agencies, power enterprises and relevant power users must attach great importance to the study and publicity of the "Regulations", strictly implement the relevant provisions of the policy, further improve the safety management level of the secondary power system, effectively strengthen the safety production of power, and ensure the safe and stable operation of the power system. .
