Interpretation Of Power Parameters Of Diesel Generator Sets

I believe that the majority of users have heard different power words such as basic power and reserve power, so do you know what they mean? In this article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will answer for you. Under the standard conditions of absolute atmospheric pressure: 89.9kPa (or altitude of 1000m), ambient temperature: 40℃, relative humidity: 60%, the power parameters of diesel generator sets are as follows several:

1. Continuous power (COP): The maximum power at which the generator set operates continuously at a constant load and the number of operating hours per year is unlimited under the agreed operating conditions and in accordance with the manufacturer's regulations.

2. Basic power (PRP): Under agreed operating conditions and maintained in accordance with the manufacturer's regulations, the maximum power at which the generator set operates continuously at a variable load and the number of operating hours per year is not limited. The average power output (Ppp) of the operation during the 24h operation period shall not exceed 70% of the PRP, unless otherwise agreed with the RIC engine manufacturer. In applications where the allowable average power output Ppp is higher than the specified value, continuous power COP should be used.

3. Limited time operating power (LTP): Under the agreed operating conditions and in accordance with the manufacturer's regulations for maintenance, the generator set can run up to a maximum power of 500h per year. According to 100% limited-time operating power, the maximum operating time per year is 500h.

4. Emergency Standby Power (ESP): Under the agreed operating conditions and the manufacturer's regulations for maintenance, once the mains is interrupted or under experimental conditions, the generator set is operated at variable load and the annual operating time can reach 200h maximum power. The allowable average power output in a 24h operating period should not exceed 70% ESP, unless otherwise agreed with the manufacturer.

Power marked on the nameplate.

Usually, the nominal output power of diesel generator set nameplate is divided into standby power (Standly Power), common power (Prime Power) and continuous power (Consecution Power).

1. Standby power is defined as the maximum power that a generator set can run continuously for 300 hours between specified maintenance periods and under specified environmental conditions, and up to 500 working hours per year. It is equivalent to the limited time operating power (LTP) in the national standard and the ISO standard. It is generally suitable for occasional emergency working conditions with large load changes such as communications and buildings.

2. Common power is defined as the maximum power in a variable power sequence with unlimited operating hours per year between the specified maintenance periods and under specified environmental conditions, which is equivalent to the national standard and ISO standard. Basic power (PRP). It is generally suitable for frequent operating conditions such as factories, mines, military forces, etc., where load changes are small.

3. Continuous power is defined as the maximum power that exists in a constant power sequence with unlimited operating time per year between specified maintenance periods and under specified environmental conditions. It is equivalent to the continuous power (COP) in the national and ISO standards. Generally, it is suitable for continuous operation conditions with minimal load changes, such as being used as a power station or connected to the mains grid.

The above are the power parameters of diesel generator sets and the power interpretation marked on the nameplate. Do you have a better understanding of diesel generator sets?
