responsibility.

More and more users of gas turbines require a trend monitoring system (TMS) with various functions on the gas turbines they purchase.

The use of TMS can improve the cost-effectiveness of the project and improve the future operation of the unit. These benefits entice users to exchange cash based on TMS

There are equipment modifications to improve the cost-effectiveness and reliability of the unit, and reduce maintenance intervals and downtime risks. The complexity of TMS can

It is determined by quoting the relevant chapters of this document.

TMS can also bring the following benefits.

---Investigate the cause of the downtime;

---Analyze the actual situation in order to prepare for maintenance in advance if necessary.

It can be foreseen from the development trend of gas turbines in recent years that it is impossible to sell gas turbines without TMS in the future, and there is a kind of

The trend of closely integrating TMS with the control system of a gas turbine.

On the one hand, the operating data in the control system is required in the TMS system, and on the other hand, the control system can quickly respond to TMS detection

Emergency. The direct combination of the two systems can provide the best solution.

There are many independent and integrated systems on the market, but they are designed based on different concepts. Correspondingly, their performance will also have

The difference. The meanings of certain terms are often contradictory and may mislead the staff.

TMS has advantages in the following aspects.

---Reduce fuel consumption;

---Optimize maintenance costs according to actual needs (such as availability);

---Minimize the impact on the environment;

---Predict the possible failures and reduce the damage or loss they may cause;

---Improve reliability and availability.

Using a unified system allows manufacturers to.

---Determine actual (not theoretical) thermodynamic data;

---Verify data and performance;

---Determine the aging of the gas turbine;

---Improve the service interval plan;

---Optimize compressor cleaning.

Operators and manufacturers can work together.

---Analyze established short-term and long-term trends;

---Conduct status analysis;

---Identify and reduce potential failures.

So that the future automatic diagnosis system can be further expanded.

With the emergence of more and more new systems, the classification and definition of technical terms have become more important. The purpose of this document is to monitor trends

The measurement system establishes certain guidelines in order to provide a basis for comparing the characteristics and performance of various systems, and to provide necessary information in the decision-making process.
