The Turbine Protection TP800 adds turbine protection capability to the System 800xA or to any other controller with Profibus interface. It provides a complete set of functions designed to address the protection requirements of most turbine types and manufacturers: „ Overspeed Protection 

„ Overspeed Trip 

„ Trip Anticipation 

„ Load Drop Anticipation 

„ 3 types of Power Load Unbalance The TP800 allows for the implementation of all common protection schemes (1oo2, 2oo3, etc).

Operational independence from the master controller results in high reliability and fast response time. Overspeed detection and trip is executed in 10 mSecs.

Automatic Overspeed Testing 

The TP800 can automatically execute an online overspeed test through the internal injection of a ramping frequency signal into the speed channels. This test verifies proper operation of the software, hardware and hydraulic components of the trip circuit.

The TP800 offers six independent relay driver outputs. A configurable matrix establishes the relationship between the protective functions and the relay drivers. In addition, each relay driver can drive one or more relays in the ROM810 modules.

Applicable Hardware 

A turbine protection system will typically include several TP800 modules. The specific number depends on the desired protection redundancy scheme. A two out of three scheme, for example, will require three TP800 modules. Each TP800 module can interface to several ROM810’s. The specific number is determined by the application characteristics. The PCM810 is only required for applications where Power Load Unbalance is calculated using generator phase current. One PCM810 module interfaces to three TP800 modules.
