19、packaged CHP products in a laboratory environment. Theoutline establishes methods for measuring, calculating, and reporting power output, efficiency, otherelectrical parameters, emissions, and thermal output with the intent of determining or verifying theoperational characteristics of the tested pro
20、ducts within the manufacturers specified ambient andoperational design limits. The outline is not a detailed procedure. It refers to detailed industry-acceptedstandards for specific test requirements, as appropriate.1.2 This document is intended for use by organizations such as manufacturers, univer
21、sities, laboratories,and other capable testing agencies to assess the performance attributes of commercial distributed energyproducts. Results of testing are ultimately intended for use by end users, manufacturers, utilities, systemintegrators, engineers, and regulators. The scope of this document c

27、UTION WITHOUT PERMISSION FROM UL2 Glossary2.1 VOLTAGE Voltage is a measure of the electromotive force or potential developed betweenseparated positive and negative electric charges. In AC circuits, the root-mean-square (rms) voltage isthe square root of the sum of the instantaneous voltage values, s
28、quared, or:in which:V = rms voltage, volts (V)T = time perioda = initial timev = instantaneous voltage, (V)For a pure sine wave, the rms voltage value is 0.7071 times the peak voltage value. Rms voltages fordistorted waveforms can differ from this proportion.2.2 CURRENT Current is a measure of the q
29、uantity of electrons flowing past a fixed point during aone-second interval. A potential difference of one volt across a one-ohm resistor causes a one-ampere(A) current to flow. Rms current in AC circuits is stated the same way as rms voltage.2.3 REAL POWER Real power is the combination of the volta
30、ge and the value of the correspondingcurrent that is in phase with the voltage. Real power produces resistive heating or mechanical work,and can be expressed as:in which:P = average real power at any time t0, watts (W)v = instantaneous voltage, (V)i = instantaneous current, (A)DECEMBER 19, 2008 SUBJ
31、ECT 3200 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULT = time periodIf both the voltage and current are sinusoidal and of the same period,P=VIcosin which:V = voltage rms value, (V)I = current rms value, (A) = phase angle between V and I,
32、(degrees)In three-phase wye-connected systems for purely resistive loads (where = 0), total power is:Ptot=(Vab/ 3)Ia+(Vbc/ 3)Ib+Vca/ 3)Icin which:Ptot= total power, (W)Vab= rms voltage between phases a and b, (V)Ia= phase a current, (A)Vbc= rms voltage between phases b and c, (V)Ib= phase b current,
33、 (A)Vca= rms voltage between phases c and a. (V)Ic= phase c current, (A)2.4 ENERGY Total energy in watt-hours is the real power integrated over the time period of interest.1000 W produced over one hour is one kilowatt-hour (kWh).2.5 REACTIVE POWER AND APPARENT POWER Reactive power develops when indu
34、ctive,capacitive, or nonlinear sources and loads exist on the system. It does not represent useful energy thatcan be extracted from the system, but it can cause increased losses and excessive voltage peaks.Reactive power is:Q=(S2P2)in which:Q = reactive power, volt-amperes reactive (VAR)S = apparent
35、 power, calculated asV*I,volt-amperes (VA)P = real power (W)DECEMBER 19, 2008SUBJECT 32008UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL2.6 POWER FACTOR Power factor, PF, is the ratio between real power and apparent power:PF = P/SPower facto
36、r indicates how much of the apparent power flowing into a load or a feeder is real power.2.7 FREQUENCY Frequency is the number of complete cycles of sinusoidal variation per unit time.In the U.S., the EPS frequency is typically 60 Hertz (Hz).2.8 TOTAL HARMONIC DISTORTION AC waveform distortion occur
37、s at integer multiples, orharmonics, of the lowest sine wave frequency (fundamental frequency). Total harmonic distortion (THD)defines the relationship of all distorting integer harmonic waveforms with the fundamental. THD is theratio of the root-mean-square (rms) summed harmonic current or voltage
38、to the rms value of thefundamental, expressed as a percent of the fundamental. In equation form:in which:%THD = total harmonic distortion (%)f = fundamental harmonic order (60 Hz in North America)h = harmonic order as an integer multiple of the fundamental (h = 2 for 120 Hz)I = true rms current (A)V
39、 = true rms Voltage (V)2.9 EXTERNAL PARASITIC LOADS Parasitic loads are those that are essential for proper DGproduct function. The power supply for some parasitic loads, such as fuel gas compressors, heatrejection unit fans, heat transfer fluid pumps, etc., may be on the customer-side, or “upstream
40、”, of theproduct power meter (see Figure 3.1). Such loads are considered to be external parasitic loads and donot factor into net product output or efficiency calculations.2.10 NORMALIZED EMISSION RATES Emission rate normalized against system power output toprovide emission rates (lb/kWh) is:DECEMBE

42、h)3 DE Boundaries3.1 A boundary diagram shall identify the equipment and components included in the system being testedand should be developed prior to testing. Figure 3.1 shows a generalized boundary diagram thatdelineates the system components, subsystems, and end user or customer interfaces. The
43、figureindicates two distinct boundaries:a) Product Boundary (DG or CHP).b) System Boundary.3.2 For the purposes of this outline, the Product Boundary is intended to identify fully functionalstandardized offerings from sellers, such as manufacturers, distributors, or dealers, and is defined as thegen
44、erating set including all skid-mounted auxiliary components supplied by the seller. In the event theproduct offered by the seller consists of multiple standardized skids requiring field assembly, all such skidsshall fall within the Product Boundary.3.3 The System Boundary is intended to identify all
45、 additional non-standard components, whethersupplied by the seller or provided by other parties, which are required to make the product fully functional.For example, if a product contains a heat recovery heat exchanger that falls within the product boundarybut does not contain the circulating pump f
46、or the thermal fluid used at the site, the circulating pump wouldfall within the System Boundary but not the Product Boundary.3.4 The boundary diagram is essential in order to identify the configuration of the system with respect toauxiliary equipment loads, referred to as “parasitic loads.” Parasit
47、ic loads, which are required for systemoperation, consume electricity and essentially reduce the system efficiency and the amount of electricpower available to an end user. It is important to delineate whether a parasitic load falls within the productor system boundary so accurate comparisons can be
48、 made between different DG systems.DECEMBER 19, 2008SUBJECT 320010UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL3.5 Auxiliary equipment that serves multiple units in addition to the DG unit being tested (such as largegas compressors) should
49、be documented in the testing report, but should not be included within theSystem Boundary unless the multiple-unit system is a standard product offering.3.6 Figure 3.1 depicts the concept of Product and System Boundaries, but it is not comprehensivebecause DG and CHP products and installations vary greatly from site to site and across applications. Foreach test performed, it is necessary to develop a detailed boundary diagram that indicates theconfiguration of the system to be tested, w
