This standard specifies the basic characteristics of reciprocating internal combustion (RIC) engines for alternating current (AC) generator sets. This standard applies to engines for (RIC) engines in ac generator sets for land and marine use, and does not apply to generator sets for aviation or driving land vehicles and locomotives. For certain special purposes (such as necessary hospital power supply, high-rise buildings, etc.), additional requirements may be necessary, and this standard stipulates that they should be used as the basis. A list of terms that define the speed regulation and speed characteristics of RIC engines is specifically applicable to engines driving generators. For other types of reciprocating prime movers (such as biogas engines, steam engines), this standard stipulates that it can be used as the basis.

ISO Foreword
50 (International Organization for Standardization) is a world-wide national standards body (ISO) joint organization of international standards. The work of formulating international standards is generally carried out through IS technical committees. Each member has the right to represent the corresponding committee on a certain material of an established technical committee. International organizations, governments and non-governmental organizations also participate in the cooperation of the same organization. They cooperate with the International Electrotechnical Commission (IEC) on all materials related to electrical standardization. The draft international standard adopted by the technical committee is circulated to the member countries of the organization. As a publication of the national standard, it requires approval by 75% of the voting members of the organization. International Standard I5(8528-1 is a product of IS/TC70 "Internal Combustion Engine Technical Requirements" SC2 Performance and Test Subcommittee, prepared by the IEC/TC70 "Internal Combustion Engine Technical Requirements" Subcommittee.

GB/T 2820.21997
4.1 Generator sets for use on deck and offshore installations powered by RIC engines not conforming to the current standards of the British Society shall meet the resistance requirements of the Society. Such groups shall be determined by the user before placing an order. The engine shall not be operated under special equipment conditions. Similar additional requirements in different cases shall be agreed between the manufacturer and the user. 4.2 If special requirements are to be met as specified by any other regulatory body (e.g. inspection and/or legislative authorities), this body shall be responsible for the production of the specified product. Any other additional requirements shall be agreed between the manufacturer and the user. 5 General characteristics
5.1 Power characteristics
The output power of the matching RI engine shall be calculated and the power required by the user for the complete equipment. The power pot, the necessary independent auxiliary equipment and the required power and 5. The power loss of the generator should be considered in addition to the total state. The power change caused by the motor vibration should be considered because they affect the power output characteristics of the engine and the electrical characteristics of the generator. Therefore, the generator set manufacturer should consider the special performance of the reverse air load and the lack of acceptance conditions of a certain load during the production period. 5.1.2150 Standard power is the continuous net effective power that the old engine can generate under the following standard conditions when it is reversed during the normal maintenance period specified by its manufacturer: 10P

This rate should be calibrated by the engine manufacturer.

GB/T2820.21997
To ensure the power supply to the connected terminals, the actual power output of the R1C engine driving the generator shall not be exceeded. To meet the positive load requirements, the R1C engine driving the generator shall temporarily output the main power. 5.2RIC.Seven characteristics of the engine
The main characteristics of the RIC engine used in the power generation system should be provided by the engine manufacturer and specified as: [S] standard thrust power and serviceability,
rated speed
fuel and lubricant consumption rate under IS standard conditions. These characteristics specified by the engine manufacturer enable the generator manufacturer and the user to confirm that they have obtained the main characteristics of the RIC engine. To determine the usable components of the generator set (especially the load), it is necessary to determine the dynamic average effective pressure of the engine corresponding to the engine speed used when the generator set is running at its rated power and rated frequency. kPa (1C0kPa=1bR:. The following formula is used to determine
Where: - For 4-stroke engines, it is 1.2×105; for 2-stroke engines, it is 1.2×105 The engine is designed to run at 0.6×10°5.3 Low and long-term load operation
Users should know that continuous operation at low load may affect the reliability and life of the RIC engine. The RIC engine manufacturer has the responsibility to provide the generator set manufacturer with the optimal low load value at which the engine or the generator can withstand long-term damage without damage. The generator set must be operated at the low load value before the low load value. The RIC engine manufacturer has the responsibility to specify and, when necessary, propose measures and/or other methods to be taken. 6 Speed ​​characteristics
6. 1. The selection of the speed control system should be based on the steady-state and group-state continuity required by the user. The generator manufacturer should select the speed control system approved by the RC engine manufacturer according to the requirements of the time. The terms of speed control are defined in 6.2 to 6.5 (see Table 4). General speed terms (see Table 1) Rated speed (stack speed) (starting speed) tt||The engine speed corresponding to the rated rated power of the generator set when the load is running

Table 3 (end)
Within the dynamic range between no-load and rated speed, the R engine planned speed versus steady-state speed curves (Figures 1 and 2) are plotted. Within the no-load and rated speed range: the speed will deviate from the recommended line, and the maximum deviation from the line will be expressed as a certain percentage of the rated speed (see Figure 2)
From RIC engine specification! The specified temporary limit engine speed is a certain safe value (see Note 1 and Figure 3)
When the speed exceeds this value, the speed limiting device will take effect. The engine speed (see Figure: ) A certain set speed is reached when the speed limiting device starts to operate (see Note 2 and Figure 3)
The total time between the start of the over-limit device and the start of its operation is not limited to the speed that the limit device can adjust.
The maximum speed is the highest calculated speed that the engine can withstand without the risk of damage. The maximum starting action rate depends on the total slowness of the engine maintenance and the improvement of the over-limit protection system. 6.6 Types of regulators used for generating sets
6-6-7 speed control program for the speed change technology related to the negative rejection of the positive stop control signal.
6.6.2 Proportional-Integral Regulator (PI) When there are load-related speed changes, the proportional-integral controller provides a positive control signal and corrects the speed change with the aid of some kind of differential operation. If this type of regulator is used, the result of the load change is usually small. The generators may be operated in parallel. If no additional load distribution regulator is provided, the PI regulator should also be used as a P regulator.
6.6.3 Proportional-Differential Regulator (P1)) The proportional-integral controller is used to calibrate the speed signal. With this type of regulator, load changes usually do not cause any speed changes. The fire makes the generator set run in parallel. If the distribution load is not provided, the PID speed regulator should also be used as the 11 speed regulator. 6.7 The speed regulator should be used as the controller (see (H/12820.1-1997 4.3) 6.7.1 Single machine operation bzxZ.net
According to the required regulation performance, P, PI and FID regulators may be selected. 6.7.2 Parallel operation

6.7.2-3 The proportional-integral-differential regulator (IIL>) should be used for G1 and G4 performance, and if the PI controller has good instantaneous performance. If it is used in the same state, an auxiliary device such as a load distribution device is required..7: With the belt receiving| |tt||The load of the R1C engine depends on the type of air supply system (GB/T2820.1-1997, 14.2).
