IEC Preface
1 The International Electrotechnical Commission is the world's leading body for standardization of electrical and electronic equipment. Its main purpose is to promote international cooperation on all matters relating to standardization in the electrical and electronic fields, to develop standards and to carry out other activities. These standards are developed by international committees on any subject of interest to the industry. International organizations, governmental and non-governmental organizations related to the International Organization for Standardization may also participate in this work. (1) The International Organization for Standardization (IOS) cooperates closely under the conditions determined by the two organizations: 2 Technical Committees - All national committees that have actual experience in the relevant technical issues shall formulate relevant technical regulations or agreements, which shall, as far as possible, express the consensus of international experts on these issues. 3) This recommendation shall be provided to the international community in the form of a recommendation or a standard, and shall be published in the form of a standard, technical report or guidance document. The relevant documents shall be recognized by the national committees. 4) To promote the selection of international work, each IEC country meeting shall agree to adopt the 12 core standards as its corresponding national and regional standards within the scope of the minimum approval and at the latest. Any disagreement between the IF standard and the corresponding national or regional standard shall be confirmed in the national or regional standard. It is pointed out that this standard is prepared by the [EC 18th International Commission on Marine Safety Equipment] for mobile and offshore installations. This standard is the 1st edition of TEC92-201, which replaces the 3rd edition published in 1980 and the 5th amendment (1U0) in accordance with the International Safety of Life Safety Convention. The standard is arranged according to the following format, document S China Office Voting Report 184 (China Executive Office 183) in the relevant ceremony: all the voting conditions of the non-standard can be found in the voting table above.

Electrical equipment should meet the following requirements:
Electrical power supply systems of 1kV~11kV equipment
6.1.1 In order to keep the working state and service conditions, and to ensure the operation of all auxiliary electrical equipment necessary for the operation of goods, this requirement must be on emergency power supply:
6.1.2 Under various emergency conditions, it can still ensure the operation of electrical equipment necessary for safety. GR/T7358-1998
6.1.3 When the generator is handed over, the starting of the motor should be restored by the new system, especially the maximum delay of the current and the voltage drop caused by the starting current must be accurate, and the output voltage drop caused by the starting current should not cause the running motor to switch or have an impact on other equipment in use.

These contents all involve the stability of the voltage rate. 6-2 Main power supply 6.2.1 The ship should be equipped with sufficient power supply to supply all the equipment mentioned in 6.1.1. The power supply points should include at least two sets of generators. 6.2.2 The quality of these generators should be such that when one of the generators stops supplying power: it can still ensure the supply of power to the necessary equipment to ensure the normal operation of the equipment; 2) to ensure the minimum safety of the equipment and cargo. The comfortable living conditions should include lighting, heating, heating and cooling, dairy and drinking water, and the amount of sanitary and drinking water. 6.2.3 The main power board at the front of the ship should be capable of maintaining the power supply of the equipment mentioned in 6.1.1 regardless of the rotation and steering of the propulsion machinery and the steering system.
If, during navigation and engine dynamics, including the thrust reverser, stops, the generators driven by the thrust reverser are sufficient to provide energy to meet the requirements of 5.3.2 and meet all further requirements, especially the requirements of 6.2.4, then these generators are accepted as generators to form the project, and the effectiveness and performance of the generators should be independent of the complete motor group. The thrust reverser that does not meet the requirements of this article can make additional plans to achieve power balance, but please note that after the power is interrupted (such as the actual stop of the thrust reverser), the power supply of the necessary machines to maintain the safe state for some period of time must not exceed the recovery time. 6.2.1 In addition, the generator or the original equipment should ensure that the remaining power generation equipment can meet the requirements of the ship's starting system. If the capacity of the power source is sufficient, it can be combined with any other power source to provide sufficient power for the emergency power supply required by the relevant authorities. If the emergency power source is not available at the same time, the generator should also be started from the new state. If the emergency power source is not available at this time, the starting equipment required by the starting group should be equivalent to the starting equipment required by the starting group. 6.2.5 If the pressure transformer, converter or similar equipment is an essential component of the system required by 5.2, the system should be arranged to ensure the continuity of its power supply and the same power supply as described in 5. E.3: In response to the requirements of relevant agencies, we should have a solid emergency resource! ! E.4.1 If the emergency power source is a generator, the generator shall be driven by an appropriate primary power source with independent fuel supply.
