acceptance test: the evaluating action(s) to determine if a new or modified piece of equipment satisfactorily meets its performance criteria, permitting the purchaser to “accept” it from the supplier. accuracy: the closeness ofagreementbetweena measured value and the true value. auxiliary power: electrical power used in the operation of the gas turbine power plant or elsewhere as defined by the test boundary. bias error: see systematic error. calibration: the process of comparing the response of an instrumentto astandardinstrumentoversomemeasure- ment range and adjusting the instrument to match the standard, if appropriate. emissions: air, solids, and water discharges from power plant systems or noise from power plant systems that are regulated by authorities having jurisdiction, such as air pollutants, waste streams, and noise. influence coefficient: see sensitivity; the ratio of the change in a result to a unit change in a parameter. instrument: a tool or device used to measure physical dimensions of length, thickness, width, weight, or any other value of a variable. These variables can include: size, weight, pressure, temperature, fluid flow, voltage, electric current, density, viscosity, and power. Sensors are included, which may not, by themselves, incorporate a display but transmit signals to remote data acquisition system or computer type devices for display, processing, or process control. Also included are items of ancillary equipment directly affecting the display of the primary instrument, e.g., ammeter shunt. Also included are tools or fixtures used as the basis for determining part acceptability.
parties to the test: for acceptance tests, those individuals designated in writing by the purchaser, lender’s engi- neer, architect engineer (or facility supplier), and machine suppliers to make the decisions required in this Code. Other agents, advisors, engineers, etc., hired by the parties to the test to act on their behalf or otherwise, may ormay notbe considered, by this Code, to be parties to the test. precision: the closeness of agreement between a group of measured values. precision error: see random error. ramp rate: the average ramp rate is the load change divided by the amount of time required to move from the initial load to the final load. The instantaneous ramp rate is the slope at a given load in the measured load change process. random error: sometimes called precision error; the true random error, which characterizes a member of a set of measurements [varies in a random, Gaussian (normal) manner, from measurement to measurement]. rated power: the power output of the power system when operating at specified control and ambient conditions. secondary variables: variables that are measured but do not enter into the calculation. sensitivity: see influence coefficient; the ratio of the change in a result to a unit change in a parameter. shutdown: the actions required to safelystop the electrical generation from an operating power producing facility. startup: the actions required to safely reach a predefined minimum load for an electrical generation facility in a shutdown or off-line condition.
3-3 TESTS 3-3.1 Preparation For acceptance and other official tests, the manufac- turer, supplier, and owner shall have reasonable oppor- tunity to examine the equipment, correct defects, and render the equipment suitable to test including manu- facturer prescribed commissioning procedures success- fully completed. The manufacturer, however, is not thereby empowered to alter or adjust equipment or con- ditions in such a way that regulations, contract, safety, or other stipulations are altered or voided. The manufac- turer may not make adjustments to the equipment for purpose of this test that may prevent immediate, contin- uous, and reliable operation at all capacities or outputs under all specified operating conditions as would other- wise be present, unless agreed to by all parties. Any actions taken that are material to the object of this Code must be documented and immediately reported to all parties to the test.
